chore: follow-up cleanup for Feishu topic thread fix

- Remove dead metadata.get('reply_to') fallback in _send_raw_message;
  nothing in the codebase ever sets 'reply_to' inside a metadata dict —
  the key only appears as a top-level send_voice() keyword argument
- Simplify _status_thread_metadata construction in run.py to use a
  single dict literal instead of create-then-mutate pattern; the
  or-{} guard was dead since source.thread_id implies _progress_thread_id
  is also set for Feishu
- Add yuqian@zmetasoft.com to AUTHOR_MAP for contributor attribution
