+- Fixed `CartesiaTTSService` failing with "Context has closed" errors when switching voice, model, or language via `TTSUpdateSettingsFrame`. The service now automatically flushes the current audio context and opens a fresh one when these settings change.

+- ⚠️ Removed deprecated service parameters and shims that have been replaced by the `settings=Service.Settings(...)` pattern or direct `__init__` parameters:
+  - `PollyTTSService` alias (use `AWSTTSService`)
+  - `TTSService`: `text_aggregator`, `text_filter` init params
+  - `AWSNovaSonicLLMService`: `send_transcription_frames` init param
+  - `DeepgramSTTService`: `url` init param (use `base_url`)
+  - `FishAudioTTSService`: `model` init param (use `reference_id` or `settings`)
+  - `GladiaSTTService`: `language` and `confidence` from `GladiaInputParams`, `InputParams` class alias
+  - `GeminiTTSService`: `api_key` init param
+  - `GeminiLiveLLMService`: `base_url` init param (use `http_options`)
+  - `GoogleVertexLLMService`: `InputParams` class with `location`/`project_id` fields (use direct init params); `project_id` is now required, `location` defaults to `"us-east4"`
+  - `MiniMaxHttpTTSService`: `english_normalization` from `InputParams` (use `text_normalization`)
+  - `SimliVideoService`: `simli_config` init param (use `api_key`/`face_id`), `use_turn_server` init param; `api_key` and `face_id` are now required
+  - `AnthropicLLMService`: `enable_prompt_caching_beta` from `InputParams` (use `enable_prompt_caching`)
