+- Added `VADProcessor` for detecting speech in audio streams within a pipeline.  Pushes `VADUserStartedSpeakingFrame`, `VADUserStoppedSpeakingFrame`, and `UserSpeakingFrame` downstream based on VAD state changes.

+- Added `vad_analyzer` parameter to `LLMUserAggregatorParams`. VAD analysis is now handled inside the `LLMUserAggregator` rather than in the transport, keeping voice activity detection closer to where it is consumed. The `vad_analyzer` on `BaseInputTransport` is now deprecated.

+  context_aggregator = LLMContextAggregatorPair(

+      user_params=LLMUserAggregatorParams(
+          vad_analyzer=SileroVADAnalyzer(),

+- ⚠️ Deprecated `vad_analyzer` parameter on `BaseInputTransport`. Pass `vad_analyzer` to `LLMUserAggregatorParams` instead or use `VADProcessor` in the pipeline.
