This change adds Git notes support to the history UI.
Commits now carry a has_note flag which triggers a note indicator.
Notes can be previewed on hover and loaded on demand,
then the history can be refreshed after edits.
- Adds has_note support on commits and parses from logs.
- Renders a note indicator in history rows with a hover preview.
- Triggers history refresh after note-related actions.
