v0.0.95

### Added

- Added ai-coustics integrated VAD (`AICVADAnalyzer`) with `AICFilter` factory and example wiring; leverages the enhancement model for robust detection with no ONNX dependency or added processing complexity.

- Added a watchdog to `DeepgramFluxSTTService` to prevent dangling tasks in case the user was speaking and we stop receiving audio.

- Introduced a minimum confidence parameter in `DeepgramFluxSTTService` to avoid generating transcriptions below a defined threshold.

- Added `ElevenLabsRealtimeSTTService` which implements the Realtime STT service from ElevenLabs.

- Added word-level timestamps support to Hume TTS service

### Changed

- ⚠️ Breaking change: `LLMContext.create_image_message()`, `LLMContext.create_audio_message()`, `LLMContext.add_image_frame_message()` and `LLMContext.add_audio_frames_message()` are now async methods. This fixes an issue where the asyncio event loop would be blocked while encoding audio or images.

- `ConsumerProcessor` now queues frames from the producer internally instead of pushing them directly. This allows us to subclass consumer processors and manipulate frames before they are pushed.

- `BaseTextFilter` only require subclasses to implement the `filter()` method.

- Extracted the logic for retrying connections, and create a new `send_with_retry` method inside `WebSocketService`.

- Refactored `DeepgramFluxSTTService` to automatically reconnect if sending a message fails.

- Updated all STT and TTS services to use consistent error handling pattern with `push_error()` method for better pipeline error event integration.

- Added support for `maybe_capture_participant_camera()` and `maybe_capture_participant_screen()` for `SmallWebRTCTransport` in the runner utils.

- Added Hindi support for Rime TTS services.

- Updated `GeminiTTSService` to use Google Cloud Text-to-Speech streaming API instead of the deprecated Gemini API. Now uses `credentials` / `credentials_path` for authentication. The `api_key` parameter is deprecated. Also, added support for `prompt` parameter for style instructions and expressive markup tags. Significantly improved latency with streaming synthesis.

- Updated language mappings for the Google and Gemini TTS services to match official documentation.

### Deprecated

- The `api_key` parameter in `GeminiTTSService` is deprecated. Use `credentials` or `credentials_path` instead for Google Cloud authentication.

### Fixed

- Fixed a `SimliVideoService` connection issue.

- Fixed an issue in the `Runner` where, when using `SmallWebRTCTransport`, the `request_data` was not being passed to the `SmallWebRTCRunnerArguments` body.

- Fixed subtle issue of assistant context messages ending up with double spaces between words or sentences.

- Fixed an issue where `NeuphonicTTSService` wasn't pushing `TTSTextFrame`s, meaning assistant messages weren't being written to context.

- Fixed an issue with OpenTelemetry where tracing wasn't correctly displaying LLM completions and tools when using the universal `LLMContext`.

- Fixed issue where `DeepgramFluxSTTService` failed to connect if passing a `keyterm` or `tag` containing a space.

- Prevented `HeyGenVideoService` from automatically disconnecting after 5 minutes.
