- Added a new animation specification document for Phase 9 Task 5 detailing the requirements for rig animation controls.
- Introduced a new `StickmanRig` script to manage the facing direction and joint bending for the rig.
- Implemented UI elements in the test harness for selecting animations, controlling playback (play/pause/resume/stop), and toggling loop mode.
- Enhanced the `test_harness.gd` script to handle animation playback state and UI interactions.
- Updated documentation in `AGENTS.md`, `README.md`, and `RIGGING.md` to reflect the new animation features.
- 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.
