## Summary by CodeRabbit

- Bug Fixes
- Releasing the mouse now always ends panning, preventing stuck states.
  - Actions cancel correctly when you release without dragging.

- Refactor
- More consistent Copilot activation: use right-click or Ctrl (⌘ on Mac)
+ left-click.
- Smoother switching to Copilot with improved drag-state reset and
cleanup.
- Removed automatic restoration of previous selection when activating
Copilot.
