test: port voice-reply suffix assertions, fix change-detector cap test, add AUTHOR_MAP entry

- Add output_path suffix assertions (.ogg Telegram / .mp3 non-Telegram) to
  _send_voice_reply tests, covering the OGG voice-note path that landed on
  main in ae82eed2b (the PR's third commit was redundant with it).
- Convert test_gemini_default_is_32000 back to an invariant against
  PROVIDER_MAX_TEXT_LENGTH instead of a hardcoded literal.
- Map barronlroth@gmail.com -> barronlroth in scripts/release.py.
