Changelog/MCP

• trash_note moves only the note you name. A revision from another note is refused, so it can't move that note instead.
• trash_note without a revision no longer leaves a conflict copy of the note at the top of the list.
• search results include each note's revision, ready for trash_note.
• Trying a recording that failed to transcribe again with the same upload_id sends it afresh, instead of repeating the failure for a day.
