Gets Gemini 3 support to the point where it works with:
- The "legacy" pattern from the previous (removed) 26- example
- inference_on_context_initialization=True (the default)
- inference_on_context_initialization=False
Add `domain` field to AssemblyAISTTSettings to support AssemblyAI's
streaming API `domain` query parameter, enabling specialized recognition
modes like Medical Mode (`medical-v1`).

Add warnings in SpeechTimeoutUserTurnStopStrategy and
TurnAnalyzerUserTurnStopStrategy when stop_secs differs from the
recommended default (0.2s) or when stop_secs >= STT p99 latency,
which collapses the STT wait timeout to 0s. Document the stop_secs=0.2
assumption in stt_latency.py.
Send a setup message with client_req_id before the first text message
for each context, matching Gradium multiplexing protocol. This allows
Gradium to associate each session with its setup configuration when
using close_ws_on_eos=False.
The AudioHook protocol requires every message to carry a `parameters`
object. `_create_message` conditionally included it only when parameters
were truthy, so pong responses and closed responses without
outputVariables were sent without the field.
Clients that validate message structure (including the Genesys reference
implementation) rejected these messages, which broke server sequence
tracking and prevented outputVariables from reaching the Architect flow.

Align with the OpenTelemetry GenAI semantic convention
gen_ai.system_instructions for system prompts. The old "system"
attribute name was unrelated to gen_ai.system (which is for
provider name).
Replace adapter-based extraction in traced_llm with direct reads from
_settings.system_instruction (priority) and context messages (fallback).
The old approach had three bugs: signature mismatch with Anthropic
adapter, key name inconsistency, and unnecessary overhead from full
message/tools conversion.
Also deduplicate the system instruction in spans -- it was appearing as
both "system" and "param.system_instruction".
These services were pushing audio frames directly via push_frame() in their
WebSocket receive loops, bypassing the base TTSService audio context
serialization queue. This causes incorrect frame ordering and broken
interruption handling.
Changes per service:
- Fish Audio: use append_to_audio_context(), replace _handle_interruption
with on_audio_context_interrupted()
- LMNT: use append_to_audio_context(), remove redundant push_frame override
- Neuphonic: use append_to_audio_context(), remove redundant push_frame and
process_frame overrides (base class handles pause/resume)
- Rime NonJson: use append_to_audio_context(), remove redundant push_frame
override
The LLMContext format already matches the expected Responses API
shape for input_audio, so no adapter conversion will be needed
once OpenAI enables support.
The API-provided full model name is more specific than the
user-provided model name (e.g. includes version/snapshot details).
Reorder the lookup in _get_model_name and add a comment where the
Responses service sets the field.
The override would re-add `instructions` after the adapter had
intentionally converted it to a developer message for empty contexts.
Added a regression test.
