• Added enhancements to NvidiaTTSService:

  • Cross-sentence stitching: multiple sentences within an LLM turn are fed into a single SynthesizeOnline gRPC stream for seamless audio across sentence boundaries (requires Magpie TTS model v1.7.0+).
  • custom_dictionary and encoding parameters for IPA-based custom pronunciation and output audio encoding.
  • Metrics generation (can_generate_metrics returns true) and stop_all_metrics() when an audio context is interrupted.
  • gRPC error handling around synthesis config retrieval (GetRivaSynthesisConfig).
