ShaderMotion motion backend

Turns a player-typed action into a ShaderMotion-encoded motion clip for a VRChat world.

API

• GET /api/motion?action=wave → {status:"ready"|"pending", slot?, job?}
• GET /api/result?job=<id> → {status, slot?, duration?}
• GET /v/slot0.mp4 → the clip for slot 0 (Range-enabled)
• POST /api/callback ← the GPU worker marks a job ready

No personal data is stored; only short action words and generated clips.
