## Summary by CodeRabbit

* **Bug Fixes**
* Improved null-safety, dependency tracking, upload validation, and
error logging for more reliable uploads, clipboard, calendar linking,
telemetry, PDF/theme printing, and preview/zoom behavior.
* Tightened handling of all-day calendar events (missing date now
reported).

* **Deprecations**
  * Removed deprecated RadioButton and RadioButtonGroup; use RadioGroup.

* **Chores**
* Unified and upgraded linting/config, reorganized imports, and
standardized binary handling for more consistent builds and tooling.
