Update to add_workers

Restyle from a bespoke dark theme to the light theme the other UI demos
share: the canonical :root tokens (--border, --muted, --highlight), the
#fafafa/#18181b body, the sticky white header with the light/red Connect
button, the fixed bottom-right #status toast, and the amber
ui-highlight-pulse keyframe. index.html drops the custom topbar wrapper for
the standard <header> plus a standalone #status element.

+- Added `pipecat.workers`, a worker-based agent framework folded in from the standalone `pipecat-subagents` package. Workers inherit from `BaseWorker`, share a `WorkerBus`, register in a `WorkerRegistry`, and exchange typed work via `@job` handlers. `LLMWorker` and `LLMContextWorker` provide ready-made LLM-driven workers. `PipelineRunner.spawn(worker)` registers fire-and-forget workers alongside the main pipeline worker.

+- ⚠️ `FrameProcessorSetup.pipeline_worker` and `FunctionCallParams.pipeline_worker` are now mandatory fields, and `FrameProcessor.pipeline_worker` raises if read before `setup()` instead of returning `None`. Real-world code (frame processors set up by `PipelineWorker`, tool handlers invoked by `LLMService`) is unaffected; only callers that construct these dataclasses by hand (typically tests) now have to supply a `pipeline_worker` reference.

+- `PipelineWorker` now inherits from `BaseWorker`, so every pipeline worker is also a bus participant. It accepts a new optional `bridged=()` parameter that auto-wraps the pipeline with bus edge processors, letting the worker exchange frames with other bridged workers over the shared `WorkerBus`. The bus is supplied by `PipelineRunner` via `worker.attach(registry=..., bus=...)` instead of through the constructor.

+- Added `LLMService.append_system_instruction(...)`, which composes durable text onto a user-provided system instruction (alongside the turn-completion and async-tool-cancellation instructions) so it is prepended on every inference and survives context-message resets.

+- Added `pipecat.workers.ui.UIWorker`, an `LLMContextWorker` that observes and drives a client GUI over the RTVI UI channel: it stores live accessibility snapshots, auto-injects `<ui_state>` into the LLM context before every inference (via the LLM's `on_before_process_frame` hook), dispatches client events to `@on_ui_event` handlers, and sends UI commands (`scroll_to`, `highlight`, `select_text`, `click`, `set_input_value`) back to the client. The optional `ReplyToolMixin` exposes a bundled `reply` tool, and `user_job_group(...)` surfaces fan-out work to the client as cancellable task cards. A native RTVI⇄bus UI bridge is built into `PipelineWorker` (active whenever RTVI is enabled), so no decorator or manual wiring is needed: inbound UI messages are broadcast on the bus as `BusUIEventMessage`, and outbound `BusUICommandMessage` / `BusUITask*` carriers are translated into RTVI frames for the client.
+
+- `UIWorker` auto-injects the UI wire-format guide (`UI_STATE_PROMPT_GUIDE`) into its LLM's system instruction by default, via a `prompt_guide` parameter — pass your own string to override the guide, or `None` to disable. Apps no longer need to concatenate `UI_STATE_PROMPT_GUIDE` into the LLM's `system_instruction` by hand.

 HTTP clients, feature flags, per-user state, observability clients,
 in-memory caches — whatever fits your app. Pipecat passes it through

 Two of the convenience aliases exercised below:
 
 - Tool handlers read it from ``FunctionCallParams.app_resources``.
 - Custom ``FrameProcessor`` subclasses read it from

 This example uses two small loggers as stand-ins for that "shared thing":
 ``ToolCallLogger`` (written from tool handlers) and
 ``TranscriptionLogger`` (written from a custom ``FrameProcessor`` that
 sits in the pipeline). A real app might just as easily pass a Postgres
 pool, a Redis client, a Stripe SDK instance, or any combination thereof.

+# Pipecat Multi-Worker Examples
+
+This directory contains example bots that use the multi-worker framework in `pipecat.workers`, `pipecat.pipeline.runner` (with `add_workers()`), and the `WorkerBus`. Each example shows a different cooperation pattern between workers: hand-off, parallel fan-out, remote workers, etc.
+
+## Setup
+
+From the repo root:
+
+```bash
+uv sync --all-extras
+source .venv/bin/activate
+cd examples/multi-worker
+```
+
+Copy the env template and fill in your API keys:
+
+```bash
+cp env.example .env
+```
+

+
+## Handoff between LLM workers
+
+Two LLM workers (greeter + support) that transfer control to each other during a voice conversation. A main worker owns the transport pipeline and bridges frames to the bus.
+
+### Running
+
+```bash
+uv run local-handoff/local-handoff-two-agents.py
+```
+
+Open <http://localhost:7860/client> in your browser to talk to your bot.
+
+To use Daily transport:
+
+```bash
+uv run local-handoff/local-handoff-two-agents.py --transport daily
+```
+
+### Overview
+
+- **[`local-handoff-two-agents.py`](local-handoff/local-handoff-two-agents.py)** — Two LLM workers (greeter + support) that hand off via `activate_worker(..., deactivate_self=True)`. The main worker owns STT, TTS, transport, and a `BusBridgeProcessor`.
+- **[`local-handoff-two-agents-tts.py`](local-handoff/local-handoff-two-agents-tts.py)** — Same shape, but each child worker ships with its own `CartesiaTTSService` in a custom pipeline. The main worker has no TTS — audio comes from whichever child is active over the bus.
+
+## Parallel debate
+
+Parallel fan-out using `worker.job_group(...)`. A voice bot takes a topic from the user, kicks off three workers in parallel (advocate, critic, analyst), waits for all three to respond, and synthesizes a balanced answer. Each worker keeps its own LLM context across rounds.
+
+### Running
+
+```bash
+uv run parallel-debate/parallel-debate.py
+```
+
+Open <http://localhost:7860/client> in your browser to talk to your bot.
+
+To use Daily transport:
+
+```bash
+uv run parallel-debate/parallel-debate.py --transport daily
+```
+
+### Architecture
+
+```
+Main worker (transport + LLM + `debate` tool)
+  └── job_group(advocate, critic, analyst)
+        └── DebateWorker (LLMContextWorker, one per role)
+```
+
+- **Main worker**: transport (STT, TTS) + LLM moderator with a `debate` direct function that fans out via `worker.job_group(...)`.
+- **Debate workers**: `LLMContextWorker`s spawned on the runner. Each keeps its own `LLMContext` across rounds and ships its completed turn back as a job response via the assistant-aggregator's `on_assistant_turn_stopped` event.
+
+## Voice code assistant
+
+Talk to your codebase hands-free. Ask questions about code, project structure, or file contents and get spoken answers based on actual files. The Claude Agent SDK worker navigates the filesystem using `Read`, `Bash`, `Glob`, and `Grep` tools.
+
+### Additional environment variables
+
+| Variable            | Required by                    |
+| ------------------- | ------------------------------ |
+| `ANTHROPIC_API_KEY` | Code worker (Claude Agent SDK) |
+| `PROJECT_PATH`      | Optional, defaults to cwd      |
+
+### Running
+
+```bash
+# Default: explores the current directory
+uv run code-assistant/code-assistant.py
+
+# Specify a project path
+PROJECT_PATH=/path/to/your/project uv run code-assistant/code-assistant.py
+```
+
+Open <http://localhost:7860/client> in your browser to talk to your bot.
+
+To use Daily transport:
+
+```bash
+uv run code-assistant/code-assistant.py --transport daily
+```
+
+### Example questions
+
+- "What does the main module do?"
+- "Find all TODO comments in the project"
+- "How is error handling implemented?"
+- "What dependencies does this project use?"
+- "Explain the test structure"
+
+### Architecture
+
+```
+Main worker (transport + LLM + `ask_code` tool)
+  └── job → CodeWorker (Claude Agent SDK)
+```
+
+- **`code-assistant.py`** — Main worker: STT, LLM (with system prompt + `ask_code` direct function), TTS, and transport. The `ask_code` tool dispatches a job to the worker via `worker.job("code_worker", payload=...)`.
+- **`code_worker.py`** — `CodeWorker`: a bus-only `BaseWorker` spawned on the runner. It accepts `@job`-style requests through the bus and runs them sequentially through a persistent Claude SDK session so follow-up questions share context.
+
+## Sensor controller
+
+Two `PipelineWorker`s side by side, communicating only over job RPC. A voice agent has a single `ask_controller(question)` tool that forwards every temperature-related request to a worker; the worker owns a simulated thermometer and its own tool-calling LLM that decides how to answer (read the current value, inspect rolling stats, change the target, change the response rate). The worker is a plain `PipelineWorker` — it does not subclass `LLMWorker` and is not bridged.
+
+### Running
+
+```bash
+uv run sensor-controller/sensor-controller.py
+```
+
+Open <http://localhost:7860/client> in your browser to talk to your bot.
+
+To use Daily transport:
+
+```bash
+uv run sensor-controller/sensor-controller.py --transport daily
+```
+
+### Example questions
+
+- "What's the temperature?"
+- "Make it warmer."
+- "Is it stable yet?"
+- "Why is it slow?" / "Speed up the response."
+- "What was the highest reading?"
+
+### Architecture
+
+```
+Voice agent (transport + STT + LLM + TTS, tool: ask_controller)
+  └── job → Controller (PipelineWorker)
+              └── SensorReader -> SensorStats -> user_agg -> llm -> assistant_agg
+```
+
+- **[`sensor-controller.py`](sensor-controller/sensor-controller.py)** — `build_sensor_controller()` returns a plain `PipelineWorker`. Jobs arrive via `@worker.event_handler("on_job_request")`, the question is queued onto the worker LLM, and the LLM's reply is paired back to the job via the assistant aggregator's `on_assistant_turn_stopped` event.
+- **[`sensor.py`](sensor-controller/sensor.py)** — Two custom `FrameProcessor` subclasses: `SensorReader` runs an autonomous tick loop that emits a `SensorReadingFrame` each second (first-order lag toward target plus Gaussian noise; mutable target and response rate); `SensorStats` maintains rolling min/max/avg/trend.
+
+# Distributed
+
+Examples where workers run across separate processes or machines.
+
+## Handoff via Redis
+
+Same two-worker handoff as the local example, but each worker runs as a separate process connected via Redis pub/sub. Requires `pip install pipecat-ai[redis]`.
+
+### Quick start (single machine, local Redis)
+
+_Terminal 1_: start Redis
+
+```bash
+docker run --rm -p 6379:6379 redis:7
+```
+
+_Terminal 2_: start the greeter worker
+
+```bash
+uv run distributed-handoff/redis-handoff/llm.py greeter
+```
+
+_Terminal 3_: start the support worker
+
+```bash
+uv run distributed-handoff/redis-handoff/llm.py support
+```
+
+_Terminal 4_: start the main transport worker
+
+```bash
+uv run distributed-handoff/redis-handoff/main.py
+```
+
+All processes connect to `redis://localhost:6379` by default.
+
+### Running across machines
+
+Point each process at the same Redis instance:
+
+_Machine A_
+
+```bash
+uv run distributed-handoff/redis-handoff/main.py --redis-url redis://your-redis-host:6379
+```
+
+_Machine B_
+
+```bash
+uv run distributed-handoff/redis-handoff/llm.py greeter --redis-url redis://your-redis-host:6379
+```
+
+_Machine C_
+
+```bash
+uv run distributed-handoff/redis-handoff/llm.py support --redis-url redis://your-redis-host:6379
+```
+
+### Architecture
+
+```
+Machine A                    Redis                    Machine B
++------------+          +-------------+          +-------------+
+| main.py    |  <---->  | pub/sub     |  <---->  |    llm.py   |
+| (transport,|          | channel:    |          |  (greeter)  |
+|  STT, TTS) |          | pipecat:acme|          +-------------+
++------------+          +-------------+          +-------------+
+                               ^                 |    llm.py   |
+                               +-------------->  |  (support)  |
+                                                 +-------------+
+```
+
+- **[main.py](distributed-handoff/redis-handoff/main.py)** — Transport worker: Daily/WebRTC, Deepgram STT, Cartesia TTS, and a `BusBridgeProcessor` over a `RedisBus`.
+- **[llm.py](distributed-handoff/redis-handoff/llm.py)** — LLM worker: runs either `greeter` or `support` with OpenAI behind a bridged `LLMWorker`.
+
+## Handoff via PGMQ (Postgres)
+
+Same shape as the Redis handoff, but the bus is backed by [PGMQ](https://github.com/tembo-io/pgmq) on a shared Postgres database (e.g. Supabase). Requires `pip install pipecat-ai[pgmq]`.
+
+### Additional environment variables
+
+| Variable       | Required by                                                          |
+| -------------- | -------------------------------------------------------------------- |
+| `DATABASE_URL` | PostgreSQL DSN (e.g. Supabase pooled connection string)              |
+| `PGMQ_CHANNEL` | Optional, channel prefix for queue names. Defaults to `pipecat_acme` |
+
+### Quick start
+
+_Terminal 1_: start the greeter worker
+
+```bash
+uv run distributed-handoff/pgmq-handoff/llm.py greeter --database-url $DATABASE_URL
+```
+
+_Terminal 2_: start the support worker
+
+```bash
+uv run distributed-handoff/pgmq-handoff/llm.py support --database-url $DATABASE_URL
+```
+
+_Terminal 3_: start the main transport worker
+
+```bash
+uv run distributed-handoff/pgmq-handoff/main.py --database-url $DATABASE_URL
+```
+
+You can also set `DATABASE_URL` in `.env` and omit the `--database-url` flag.
+
+### Architecture
+
+Same as the Redis handoff above; the `RedisBus` is replaced by a `PgmqBus`, and the "pub/sub channel" is a set of PGMQ queues on the shared Postgres instance.
+
+## LLM worker via WebSocket proxy
+
+Runs an LLM worker on a remote server, connected to the main transport worker via a WebSocket proxy. No shared bus required — the proxy workers forward bus messages point-to-point over the WebSocket.
+
+### Quick start (single machine)
+
+_Terminal 1_: start the remote assistant server
+
+```bash
+uv run remote-proxy-assistant/assistant.py
+```
+
+_Terminal 2_: start the main transport worker
+
+```bash
+uv run remote-proxy-assistant/main.py --remote-url ws://localhost:8765/ws
+```
+
+Open <http://localhost:7860/client> in your browser to talk to the bot.
+
+### Running across machines
+
+_Server machine_: start the assistant
+
+```bash
+uv run remote-proxy-assistant/assistant.py --host 0.0.0.0 --port 8765
+```
+
+_Client machine_: point at the server
+
+```bash
+uv run remote-proxy-assistant/main.py --remote-url ws://server-host:8765/ws
+```
+
+### Architecture
+
+```

+  ═════════════════════════════════════         ═════════════════════════════════════════
+```
+
+- **[main.py](remote-proxy-assistant/main.py)** — Transport worker with STT, TTS, and a `BusBridge`. Spawns a `WebSocketProxyClientTask` that connects to the remote server and forwards `BusFrameMessage`s.
+- **[assistant.py](remote-proxy-assistant/assistant.py)** — FastAPI server. Each WebSocket connection spawns a `WebSocketProxyServerTask` plus a bridged `AcmeAssistant` LLM worker on a per-session `PipelineRunner`.
+
+### Security
+
+The proxy workers filter messages by worker name:
+
+- Only messages targeted at the remote worker cross the WebSocket
+- Only messages targeted at the local worker are accepted from the WebSocket
+- Broadcast messages never cross the WebSocket
+
+Pass HTTP headers for authentication:
+
+```python
+proxy = WebSocketProxyClientTask(
+    "proxy",
+    url="wss://server-host:8765/ws",
+    remote_worker_name="assistant",
+    local_worker_name="acme",
+    headers={"Authorization": "Bearer <token>"},
+)
+```

+
+Two ``PipelineWorker`` instances run side by side:
+
+- The **voice agent** is built inline in ``run_bot`` — a standard
+  transport + STT + LLM + TTS pipeline. Its LLM has a single tool,
+  ``ask_controller(question)``, which forwards the user's request to
+  the controller over the bus and speaks back the response.
+- The **sensor controller** (``build_sensor_controller``) is a
+  ``PipelineWorker`` whose pipeline runs a simulated temperature sensor
+  (see ``sensor.py``) alongside its own LLM. The worker LLM has tool
+  access to read the current reading, inspect rolling stats, and
+  mutate the simulated sensor's target temperature and response rate.
+
+The worker does **not** subclass ``LLMWorker`` and is **not** bridged.
+The voice agent and the controller communicate exclusively through
+``BusJobRequestMessage`` / ``BusJobResponseMessage``. The controller
+collects responses by listening to the assistant aggregator's
+``on_assistant_turn_stopped`` event and pairing each LLM completion
+with the in-flight job id.

+# async-tasks
+
+The UIWorker fans out long-running work to multiple peer workers in
+parallel, streams their progress to an in-flight panel on the page, and
+lets the user cancel mid-flight.
+
+## What it shows
+
+- The **`user_job_group` / `start_user_job_group`** API: dispatching
+  parallel work to multiple peer workers and automatically forwarding
+  every job lifecycle event to the client. The `reply` tool calls
+  `start_user_job_group("wikipedia", "news", "scholar", payload=...,
+  label=...)` and the `UIWorker` does the rest.
+- The four **`ui-task` envelopes** the worker forwards (`group_started`,
+  `task_update`, `task_completed`, `group_completed`) and the
+  client-side `RTVIEvent.UITask` event for consuming them. The client
+  keeps a state map keyed by `task_id` and renders per-worker progress.
+- **Cancellation**: the in-flight card's Cancel button calls
+  `client.cancelUITask(task_id, reason)`. The reserved `__cancel_task`
+  event is translated by the `UIWorker` into `cancel_job_group(task_id)`
+  on the registered group; cancelled workers report status `cancelled`.
+- **Background dispatch from a tool**: `start_user_job_group` returns
+  immediately so the `reply` tool can speak its acknowledgement
+  ("Researching the Mariana Trench now") while the workers run — the
+  main LLM is free to take follow-up turns.
+
+## What it adds vs. the prior demos
+
+The other examples use the request/response half of the bus protocol
+(main LLM → UIWorker → reply). This one adds the streaming job-group
+half: UIWorker → peer workers → progress events forwarded to the client.
+The architecture grows from "one delegate" to "one delegate plus a
+worker pool" — the peers are plain `BaseWorker`s launched on the runner.
+
+## Run
+
+Two terminals.
+
+**Terminal 1 — bot:**
+
+```bash
+cd examples/multi-worker/ui-worker/async-tasks
+uv run python bot.py
+```
+
+The bot starts on `http://localhost:7860`.
+
+**Terminal 2 — client:**
+
+```bash
+cd examples/multi-worker/ui-worker/async-tasks/client
+npm install            # one-time
+npm run dev
+```
+
+Open `http://localhost:5173` and click **Connect**.
+
+## What to try
+
+The workers are simulated (canned summaries, randomized `asyncio.sleep`
+delays) so the demo focuses on the protocol, not the AI. Each research
+call takes a few seconds.
+
+- _"Research the Mariana Trench."_ — the worker spawns three peers,
+  acknowledges in one short reply, and a card appears showing each
+  peer's status as it progresses (searching → found N results →
+  summarizing → completed).
+- _"Look up octopus cognition."_ — same flow; a second card stacks.
+- _"Research the moon, then research Mars."_ — two groups run
+  concurrently.
+- _"How are you?"_ (no research) — quick reply, no job group.
+- **Click Cancel on an in-flight card** — the cancellation routes
+  through, the peers' tasks raise `CancelledError`, and their responses
+  come back as `cancelled`.
+
+## Requirements
+
+- `OPENAI_API_KEY`
+- `DEEPGRAM_API_KEY`
+- `CARTESIA_API_KEY`
+
+A `.env` in the example folder is the easiest way to set these (see
+`examples/multi-worker/env.example`).
+
+## What this example _doesn't_ show
+
+Real worker integrations (the peers are simulated), LLM-driven peers
+(these are pure data-fetch — a peer can itself be an `LLMWorker`),
+streaming chunks (`send_job_stream_data` for progressive output), or
+worker-to-worker fan-out (nested job groups).
