- Remove overly broad 'not found' match that could trigger on transient
errors like 'chat not found' or 'message to reply not found'
- Keep only 'method not found' and 'unknown method' which indicate
the server genuinely doesn't support sendRichMessage
- Demote timeout log from warning to debug since it falls back to
legacy path successfully
- Try sendRichMessage for all non-blockquote messages (tables, task lists,
math, collapsible, etc.) with graceful fallback to legacy HTML
- Fix payload format to use top-level 'markdown' field per Bot API 10.1 spec
- Add rich path in send_delta() stream end (delete preview + send rich)
- Latch off permanently if server returns capability error
- Removes _needs_rich_rendering() gate and 4 regex patterns
Add support for Xiaomi MiMo ASR as a third transcription backend alongside
Groq and OpenAI Whisper. Xiaomi ASR uses the /v1/chat/completions endpoint
with base64-encoded audio input, rather than the standard Whisper multipart
upload format.
