kshitijk4poor 2cd952e110 feat(stt): add register_transcription_provider() plugin hook
Add an opt-in Python plugin surface for speech-to-text backends,
mirroring the TTS hook pattern. New backends (OpenRouter, SenseAudio,
Gemini-STT, custom proprietary engines) can be implemented as plugins
without modifying tools/transcription_tools.py.

Built-ins always win
--------------------
The 6 built-in STT providers (local/faster-whisper, local_command,
groq, openai, mistral, xai) keep their native handlers. Plugins
attempting to register under a built-in name are rejected at
registration time with a warning and re-checked defensively at
dispatch.

Resolution order
----------------
1. stt.provider matches a built-in → built-in dispatch (unchanged)
2. stt.provider matches a registered plugin →
   a. if plugin.is_available() returns False → unavailability envelope
      identifying the plugin (not the generic "No STT provider"
      message — the user explicitly opted into this plugin)
   b. otherwise plugin.transcribe() with model + language forwarded
      from stt.<provider>.{model,language} config
3. No match → legacy "No STT provider available" error (unchanged)

Per-provider config namespace
-----------------------------
Plugins read their config from stt.<provider> in config.yaml, mirroring
how built-ins read stt.openai.model / stt.mistral.model. The dispatcher
forwards `model` and `language` from this section. Caller's explicit
`model=` argument overrides the config-set model.

Behavior parity
---------------
10 scenarios, 8 OK + 2 expected DIFFs:
  no_provider_error → plugin (plugin-installed scenario)
  no_provider_error → plugin_unavailable (plugin-installed-unavailable
  scenario; PR returns cleaner envelope)
Zero behavior change for users not opting into a plugin.

Issue follow-up to #30398.
