• Fixed TTSSpeakFrame(append_to_context=True) greetings sometimes splitting across two assistant messages in the LLM context and not surfacing in on_assistant_turn_stopped. The LLMAssistantPushAggregationFrame emitted at the end of a TTS context now carries a PTS just past the last word so it can't overtake clock-queued TTSTextFrames in the transport's output, and LLMAssistantAggregator now triggers on_assistant_turn_started/on_assistant_turn_stopped when it receives the frame outside an LLM response cycle (restoring v0.0.104 behavior for greeting transcripts).
