Add StkRigAdapter for runtime skeleton fitting and shape mounting

Browse Source 
- Implemented StkRigAdapter class to adapt a master rig to a loaded .stk dictionary.
- Added methods for fitting bone lengths, recalibrating IK targets, and mounting vector shapes.
- Defined constants for default proportions and bone paths.
- Included error handling for missing nodes and invalid data structures.
