Fold BaseTask.handoff_to into activate_task(deactivate_self=...)

Browse Source 
BaseTask.handoff_to was just deactivate_self + activate_task. Remove
it and add a deactivate_self flag on activate_task instead, so there's
one entry point for activating another task.

LLMTask now overrides activate_task (mirroring its end() override) to
keep the messages / result_callback hooks that finish an in-progress
tool call before the target is activated. All multi-task examples and
unit tests switch to the new call.

### Overview
- **[`local-handoff-two-agents.py`](local-handoff/local-handoff-two-agents.py)** — Two LLM tasks (greeter + support) that hand off via `BaseTask.handoff_to(...)`. The main task owns STT, TTS, transport, and a `BusBridgeProcessor`.
- **[`local-handoff-two-agents.py`](local-handoff/local-handoff-two-agents.py)** — Two LLM tasks (greeter + support) that hand off via `activate_task(..., deactivate_self=True)`. The main task 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 task ships with its own `CartesiaTTSService` in a custom pipeline. The main task has no TTS — audio comes from whichever child is active over the bus.
