- Introduce NoteMode enum { view, edit, preview } replacing the old bool
- Default mode when opening a note is view (syntax-highlighted, read-only)
- Menu now shows all three modes with a checkmark on the active one
- Save and autosave menu items disabled outside edit mode
- New notes open in edit mode with cursor positioned after the header
and keyboard focused, ready to type
