Adds `enable_prompt_caching` setting to `AWSBedrockLLMSettings`. When
enabled, appends `cachePoint` markers to system prompts and tool
definitions in ConverseStream requests.
This can reduce TTFT by up to 85% for multi-turn conversations where
the system prompt stays constant (e.g. voice agents, chat assistants).
Follows the same pattern as `AnthropicLLMService.enable_prompt_caching`.
Usage:
```python
llm = AWSBedrockLLMService(
settings=AWSBedrockLLMSettings(
model="au.anthropic.claude-haiku-4-5-20251001-v1:0",
enable_prompt_caching=True,
),
)
```

Remove EmulateUserStartedSpeakingFrame, EmulateUserStoppedSpeakingFrame
(deprecated since v0.0.99), and the emulated field from
UserStartedSpeakingFrame and UserStoppedSpeakingFrame. Clean up the
handling code in base_input.py and a stale comment in nova_sonic/llm.py.
The interruption_strategies mechanism was deprecated in v0.0.99 in favor
of LLMUserAggregator's user_turn_strategies. All evaluation logic was
already removed — this removes the remaining field definitions, property,
StartFrame propagation, conditional check in base_input.py, strategy
files, and test.
This field was deprecated in v0.0.99 in favor of LLMUserAggregator's
user_turn_strategies / user_mute_strategies parameters. Since the default
was True (interruptions allowed), removing the guards keeps the current
default behavior.
The location and project_id fields were deprecated since 0.0.90 in
favor of direct __init__ parameters. Now that InputParams is removed,
project_id is required and location defaults to "us-east4" directly
in the signature.
Override _update_settings in CartesiaTTSService to flush the current
audio context and assign a new turn context ID when voice, model, or
language settings change. This prevents Context has closed errors
from Cartesia API, which locks these parameters per context.
Remove the deprecated text_aggregator parameter from TTSService,
CartesiaTTSService, and RimeTTSService, and the deprecated text_filter
parameter from TTSService. Users should use LLMTextProcessor before
the TTS service instead. Update the voice-switching example to use
LLMTextProcessor with PatternPairAggregator.
