Update PAL Bend Player Tools to 0.4.1

[kltyton]

Updates PAL Bend Player Tools from 0.4.0 to 0.4.1, matching the current source repository.

• Preserve animation-local hierarchy, loop return time, and PAL metadata from the updated Blender exporter.
• Retain per-axis easing and Bezier handles, mirror value offsets correctly, and support sparse pal.disabled tracks.
• Sample curved transforms at 60 Hz when converting rig hierarchies; direct tracks keep their easing parameters.

Validation: JavaScript syntax check, repository plugin validator, and all 7 existing Blender contract tests passed against the submitted plugin file.
