- Add dedicated Settings subclasses to 20 LLM services that were
borrowing parent Settings classes (e.g. AzureLLMSettings,
GroqLLMSettings) so users don't need cross-module imports
- Fix field defaults to NOT_GIVEN in BaseWhisperSTTSettings,
OpenAIRealtimeSTTSettings, and NvidiaSegmentedSTTSettings for
delta-mode safety
- Fix incomplete default_settings in AWS, Cartesia, ElevenLabs,
Fish, and Whisper services so validate_complete() passes
- Add auto-discovered tests that verify all Settings classes default
to NOT_GIVEN (delta safety) and all services initialize with
complete settings (store completeness)
