## Summary of the Pull Request
This PR introduces a scaled-down version of the global error handler
from #41061.
- Catches and logs virtually all unhandled exceptions.
- For UI thread exceptions, generates an additional error report:
- One copy is saved in app's log folder for the Bug Report Tool.
- Another copy can be placed to the user’s desktop to increase
visibility and encourage report submission (disabled for now).
- Displays a message box that tells the user where to find the saved
report.
This PR is intentionally minimal and focused. The complete, more
polished solution is still planned in #41061, which should replace this
implementation in a follow-up.
