+- Added model-specific `InputParams` to `RimeTTSService`: arcana params (`repetition_penalty`, `temperature`, `top_p`) and mistv2 params (`no_text_normalization`, `save_oovs`, `segment`). Model, voice, and param changes now trigger WebSocket reconnection.

+- ⚠️ `RimeTTSService` now defaults to `model="arcana"` and the `wss://users-ws.rime.ai/ws3` endpoint. `InputParams` defaults changed from mistv2-specific values to `None` — only explicitly-set params are sent as query params.
