Refine jump logic and add difference tracking

- Introduce `_shouldJump` and `_previousDifference` for smoother jump control.
- Add `_initDifference` to reset difference tracking after each jump.
- Refactor jump mechanics into a dedicated `Jump` method.
- Adjust physics raycast distance for better collision detection.
- Enhance `DebugUi` with updated difference and velocity tracking.
