fix voice memos and move metadata to properties

- Fix duplicate tab bug via onNoteCreatedRef (stale closure in recorder.onstop)
- Fix transcription not showing: read file from disk and update editor directly
- Move voice memo type/recorded/path from body to YAML frontmatter (Properties)
- Update note creation agent to detect voice memos via frontmatter
