The skinned player model was loading miku_rigged_final.glb which only
contained a single "Idle" animation (1 track, near-rest pose). This caused
"animation 'Jump/Walk/Run' not found" spam and a T-pose appearance.
Switch to miku_rigged_animated.glb which has all 7 animations
(Crouch, Death, Idle, Idle2, Jump, Run, Walk).
Additional fixes:
- Fix scaling: the GLB is already in meters (~1.6m tall), not cm.
Removed the unconditional 0.01 cm->m conversion that was shrinking
the character to 1/100th size.
- Fix bone track paths: use "MikuRig/Skeleton3D:" prefix matching the
actual scene tree structure (AnimationPlayer is sibling of MikuRig).
- Add _ensure_locomotion_animations() to create Walk/Run/Jump/Idle
procedurally if the GLB is missing them.
- Eliminate per-frame "not found" log spam with rate-limited warnings.
- Update level_runtime.gd and test_level_builder.gd to use animated GLB.
Closes #3d-player-model animation pipeline
