## Summary of the Pull Request
This pull request updates the tray icon context menu logic to better
reflect the state of the "Quick Access" feature. The menu now
dynamically updates its items and labels based on whether Quick Access
is enabled or disabled, improving clarity for users.
**Menu behavior improvements:**
* The tray icon menu now reloads itself when the Quick Access setting
changes, ensuring the menu always matches the current state.
* The "Settings" menu item label changes to "Settings\tLeft-click" when
Quick Access is disabled, providing clearer instructions to users.

* The Quick Access menu item is removed from the context menu when the
feature is disabled, preventing confusion.
**Internal state tracking:**
* Added a new variable `last_quick_access_state` to track the previous
Quick Access state and trigger menu reloads only when necessary.

## Validation Steps Performed
Enhanced SanitizeAndNormalize to handle Unicode normalization more
robustly, ensuring correct buffer sizing and error handling. Added unit
tests for regex metacharacters `$` and `^` to verify correct replacement
behavior at string boundaries. Improves Unicode support and test
coverage for regex edge cases.
