_filterNotes was calling note.readAsStringSync() and _extractTags() for
every note on every keystroke, plus recomputing path.relative() each
time. For large collections with many subdirectories this is O(n * disk).
Fix: build three maps during _loadNotes (which already reads every file
once) and use them in _filterNotes instead of touching the filesystem:
- _noteRelativePaths: pre-lowercased relative path per note
- _noteContentLower: pre-lowercased content for full-text search
- noteTags: already existed, now actually used in filter
_filterNotes now does only in-memory map lookups and string.contains
checks — no file reads, no regex, no path computation per keystroke.
Also fix _createNewNote: the Navigator.push was not awaited so
_loadNotes() was never called on return, leaving stale caches after
editing a freshly created note. Now awaits the push and reloads on
return, mirroring the existing-note tap behaviour.

_filterNotes lowercases the query so searchTags contains e.g. '#work',
but _extractTags preserves original case from file content ('#Work').
The startsWith comparison was case-sensitive, causing all tag searches
to fail whenever the file used any uppercase in tag names.
Fix: toLowerCase() on the noteTag side before comparing.

- filter notes by relative path instead of bare filename so searching
"/subdir" or "subdir" matches notes inside that subdirectory
- strip leading "/" from search text before matching so both forms work
- tighten tag regex in _extractTags and _formatTags: require a letter
after the symbol and a non-word boundary before it ((?<!\S)) to avoid
matching phone numbers (+44…) and email-local-part suffixes
- fix subdir/notename creation: use contains('/') instead of
startsWith('/') so names without a leading slash are split correctly

- 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
