fix: show new (untracked) notes in Changes view (#161)

* fix: show new (untracked) notes in Changes view

Two fixes:
1. Use `git status --porcelain --untracked-files=all` so individual
   untracked files in subdirectories are listed (instead of just the
   directory name, which gets filtered out by the .md extension check).
2. Call loadModifiedFiles after persistOptimistic completes, so notes
   created via handleCreateNote/handleCreateType appear in Changes
   immediately without requiring a manual Cmd+S.
