* feat(asr): add chat audio remote benchmarking
* style(asr): apply black formatting
* test(main): include remote API model kwarg
* test(asr): add coverage for chat-completions error handling and parsing
Add 10 new tests to cover uncovered lines in PR #468:
- ConnectionError handler in _try_chat_completions_audio_api (lines 1601-1602)
- _parse_chat_completion_transcription edge cases: None, list content,
empty/whitespace strings, JSON without text field, plain text, and
single-line language metadata (lines 1610, 1613-1621, 1625, 1629-1640)
Coverage for recognition_manager.py improved from 85% to 86%.
* feat(asr): support FunASR remote responses
* refactor(asr): scope remote FunASR support to the #469 path
Drop chat-completions/Qwen client, evaluation notes, and the remote ASR
benchmark harness. Keep model field, tolerant OpenAI response parsing,
SenseVoice label stripping, FunASR docs, and tests.
