Subject: [PATCH 01/26] Fix SSE server connection handling for MCP client

### Summary
This PR improves the MCP (Model Context Protocol) client's SSE (Server-Sent Events) server connection handling by replacing the generic string parameter with a proper `SseServerParameters` class.

### Changes
- **Breaking Change**: Changed `server_params` type from `Union[StdioServerParameters, str]` to `Union[StdioServerParameters, SseServerParameters]`
- Added import for `SseServerParameters` from `mcp.client.session_group`
- Updated SSE client connection to use structured parameters instead of a simple URL string
- Fixed error message to correctly reflect the expected parameter types
- Improved logging by changing info-level log to debug-level for consistency

### Details

#### Before
The SSE client connection only accepted a URL string:
```python
async with self._client(self._server_params) as (read, write):
```

#### After
Now properly unpacks SSE server parameters:
```python
async with self._client(
    url=self._server_params.url,
    headers=self._server_params.headers,
    timeout=self._server_params.timeout,
    sse_read_timeout=self._server_params.sse_read_timeout
) as (read, write):
```

### Benefits
- **Type Safety**: Stronger type checking with dedicated `SseServerParameters` class
- **Extended Configuration**: Support for custom headers (authentication), timeouts, and SSE-specific settings
- **Better Error Messages**: Clear type error messages when incorrect parameters are provided
- **Improved Debugging**: Debug logging of SSE server parameters for troubleshooting

### Migration Guide
Users need to update their SSE server initialization:
```python
# Before
client = MCPClient("https://example.com/sse")

# After
from mcp.client.session_group import SseServerParameters
client = MCPClient(SseServerParameters(
    url="https://example.com/sse",
    headers={"Authorization": "Bearer token"},
    timeout=30,
    sse_read_timeout=60
))
```

### Testing
- [ ] Tested with StdioServerParameters (unchanged behavior)
- [ ] Tested with SseServerParameters with various configurations
- [ ] Verified error handling for invalid parameter types

---

This is a necessary change to support production-ready SSE connections with proper authentication and timeout handling.

Subject: [PATCH 05/26] Fix missing video_in_enabled in vision bot.py for
 Moondream template

The parameter video_in_enabled=True was missing in DailyParams, which prevented image capture
from working. Without this parameter, UserImageRequestFrame would be sent but no actual image data would be captured from participants.

This fix enables the "Let me take a look" functionality to work as
intended by allowing the transport to capture video frames for vision processing with Moondream.

+# Freeze Test Client
+
+The purpose of this example is to create an environment for testing the bot and try to create freezing conditions.
+
+### Approach 1: Server-Side Testing with `SimulateFreezeInput`
+
+- Utilize only the bot `freeze_test_bot.py` with the `SimulateFreezeInput` processor. This input continuously injects frames, simulating user speech interruptions at random intervals.
+- This approach excludes the use of input transport and speech-to-text (STT) functionalities.
+
+### Approach 2: Server-Side with TypeScript Client
+
+- Combine server-side operations with a TypeScript client.
+- The client initially records a segment of audio, e.g., 5–10 seconds long. It can be anything.
+- After that, it replays this recorded audio to the server at random intervals, mimicking user input interruptions.
+- This helps testing interruptions in the pipeline as if real users were interacting with the bot.
+
+## Setup
+
+Follow these steps to set up and run the Freeze Test Client:
+
+1. **Run the Bot Server**  
+   - Set up and activate your virtual environment:
+       ```bash
+       python3 -m venv venv
+       source venv/bin/activate  # On Windows: venv\Scripts\activate
+       ```
+
+   - Install dependencies:
+      ```bash
+      pip install -r requirements.txt
+      ```
+
+   - Create your `.env` file and set your env vars:
+      ```bash
+      cp env.example .env
+      ```
+   
+   - Run the server:
+      ```bash
+      python freeze_test_bot.py
+      ```
+
+2. **Navigate to the Client Directory**
+   ```bash
+   cd client
+   ```
+
+3. **Install Dependencies**
+   ```bash
+   npm install
+   ```
+
+4. **Run the Client Application**
+   ```bash
+   npm run dev
+   ```
+
+5. **Access the Client in Your Browser**  
+   Visit [http://localhost:5173](http://localhost:5173) to interact with the Freeze Test Client.

+- `HeartbeatFrame`s are now control frames. This will make it easier to detect
+  pipeline freezes. Previously, heartbeat frames were system frames which meant
+  they were not get queued with other frames, making it difficult to detect
+  pipeline stalls.
+
 - Updated `OpenAIRealtimeBetaLLMService` to accept `language` in the
   `InputAudioTranscription` class for all models.

 ### Added
 
+- Introduce task watchdog timers. Watchdog timers are used to detect if a
+  Pipecat task is taking longer than expected (by default 5 seconds). It is
+  possible to change the default watchdog timer timeout by using the
+  `watchdog_timeout` constructor argument when creating a `PipelineTask`. With
+  watchdog timers it is also possible to log how long each processing step is
+  taking (e.g. processing an element from a queue inside a task). This is done
+  with the `enable_watchdog_logging` constructor argument when creating a
+  `PipelineTask.` It is also possible to control these two values per each frame
+  processor. That is, you can set set `enable_watchdog_logging` and
+  `watchdog_timeout` when creating any frame processor through their constructor
+  arguments. Finally, you can also set these values per task. So, if you are
+  writing a frame processor that creates multiple tasks and you only want to
+  enable logging for one of them, you can do so by passing the same argument
+  names to the `FrameProcessor.create_task()` function. Note that watchdog
+  timers only work with Pipecat tasks but not if you use `asycio.create_task()`
+  or similar.
+
 - Added `lexicon_names` parameter to `AWSPollyTTSService.InputParams`.
 
 - Added reconnection logic and audio buffer management to `GladiaSTTService`.

 ### Fixed
 
+- Fixed an issue in `FastAPIWebsocketClient` to ensure proper disconnection 
+  when the websocket is already closed.
+
+- Fixed an issue where the `UserStoppedSpeakingFrame` was not received if the
+  transport was not receiving new audio frames.
+
+- Fixed an edge case where if the user interrupted the bot but no new aggregation 
+  was received, the bot would not resume speaking.

 - Fixed an issue with `ElevenLabsTTSService` where the context was not being
   closed.
