Replace static arrow.png with dynamically generated SVG arrows that match
the source object's color from the toolbox palette.
Changes:
- Replace arrow.png loading with inline SVG generation (32x32 right-pointing triangle)
- Add CreateColoredTexture() method to generate arrows in any hex color
- Extract color from source mesh using three-priority fallback system:
1. mesh.metadata.color (most reliable)
2. sourceMesh.id parsing (e.g., "tool-#box-template-#FF0000")
3. material color extraction (backwards compatibility)
- Match extracted color to closest of 16 toolbox colors using Euclidean distance
- Track all textures in Set for synchronized animation
- Add proper texture disposal to prevent memory leaks
Benefits:
- No external arrow.png dependency
- Connections visually match their source object's toolbox color
- Consistent 16-color palette across all connections
- Efficient texture sharing for matching colors
- SVG scales perfectly at any resolution
