Subject: [PATCH] perf: optimize shouldRepaint in MeshRadar _SweepingDotPainter

Updated the `shouldRepaint` method in `_SweepingDotPainter` (within `lib/ui/mesh_radar.dart`) to check for changes to static properties rather than unconditionally returning `true`. This prevents unnecessary canvas repaints whenever the parent widget rebuilds, improving UI performance. The dynamic animation is still handled by the `repaint` listenable passed to the `super` constructor.

Also added a journal entry in `.jules/bolt.md` documenting this performance optimization pattern.
