v0.0.1-alpha.3

Menus and transcripts follow the family panel contract. Long voices keep
Deepgram paragraph breaks.

Added

• Menu callbacks are owner-scoped (m:<user_id>:<action>). A foreign tap is
  ignored with a short toast.
• Close deletes the panel instead of replacing it with a checkmark.
• Empty stats show a short empty state, not zeros.
• Deepgram Listen requests paragraphs=true. The formatted reply uses that
  paragraph text when Deepgram returns it.

Changed

• /start, Help, and Stats use <b>title</b> + <i>hint</i> +
  <blockquote> body, with Back/Close on subpanels.
• Transcripts are a clean blockquote. Language, duration, and confidence are
  no longer appended.

Known Limitations

• Cached transcripts from earlier alphas stay a single paragraph until that
  file_id is transcribed again.
