Add validated G1 kinematic motion lab and remote retargeting kit

[daitomanabe]

Summary

• Add G1 Motion Lab: real Unitree model-derived geometry, source-skeleton comparison, hand trails, and explicit kinematic-only status.
• Include independently validated full A/B/C references: 1,299 original dance frames each at 40 Hz; pinned source/model/URDF hashes and quantitative reports.
• Keep links rigid between frames with parent-relative quaternion interpolation.
• Provide a separate, pinned remote retargeting reproduction kit with temporal branch selection and strict independent export gates.
• Extend build/render/invalid-input tests and preserve original performance data and third-party rights.

Verification

• Nine openFrameworks 0.12.1 Release applications and existing regressions built locally.
• Final G1 Make and Xcode Release builds passed; four accepted-data captures and 22 invalid-input cases passed.
• Interpolation checked across all 3,894 adjacent-frame intervals; maximum rigid-anchor error 0.000143 mm.
• All full A/B/C pose gates passed an independent re-evaluation. Thresholds were not relaxed.
• Actual render screenshot and complete pose/provenance reports are included.

Safety and scope

This is not a robot controller. A separate bounded physics experiment failed its self-contact penetration gate. The viewer always states that physics is not validated; no robot SDK, DDS connection, policy checkpoint or actuator commands are included. No paid cloud resources were used. The MIT license applies to new code, not the original/derived performance data or Unitree geometry.
