v0.1.1

Added

• Perplexity requests carry an X-Pplx-Integration: flowcat header so the
  traffic can be identified in provider telemetry; the shared OpenAI-compatible
  client gained an opt-in headers builder (other providers are unchanged).
• Full-duplex support for the cascaded pipeline, KittenTTS (self-hosted), NVIDIA
  Riva STT, Sarvam STT/TTS model and language options, and ContextRelay
  long-call memory for realtime calls.

Changed

• Dependency updates (rubato 4, str0m 0.21, tokio-tungstenite 0.30, and others)
  and fixes for newer Rust 1.99 clippy lints.
