fix: textured Miku model + ragdoll color

- Re-exported Miku with properly mapped textures (9.8MB GLB)
- Texture files saved alongside GLB for Godot import
- Fixed Blender 5.0 API: 'Base Color' (not 'BaseColor'), major_segments (not segments)
- Ragdoll now uses Miku teal color (0.0, 0.75, 0.75)
- Player 1 uses SkinnedPlayerModel (no procedural generation)
- Other players still use procedural HumanoidModel
