feat: Implement facing profiles and bend direction toggles in test harness

Browse Source 
- Added functionality for skeleton IK bone switches, allowing users to dynamically change the bend direction of joints via a context menu.
- Introduced facing profiles (LEFT, RIGHT, FORWARD) that modify the bend direction of limbs based on the selected profile.
- Implemented body part z-ordering based on the facing profile, ensuring correct rendering order of limbs relative to the torso.
- Added a coordinates display panel that shows the position and rotation of the Skeleton2D and its bones, as well as IK target positions.
- Created a new script to generate a walk animation for the stickman rig, including keyframe tracks for various IK targets.
- Updated documentation to reflect the new features and their specifications.
