Refactor jump mechanics and timer logic

- Replace `_upJumpQueued`, `_jumpInputBuffer`, and redundant joint drive logic with streamlined `_jumpTimer`, `_jumpTimerMilliseconds`, and `_jumpTimerFinished`.
- Improve jump handling by introducing `_shouldJump` and `_canJump` with timer-based reset.
- Remove unused joint configuration and redundant variables for cleaner implementation.
- Update `SampleScene` with new jump parameters for better tuning.
