Default visualization was unreadable because every node from depth 0 to
maxDepth was rendered with rainbow-coloured edges. Add three filters
exposed in the Debug folder:
- Octree Leaves Only (default true): skip internal nodes
- Octree Min Depth (default 4): hide the largest enclosing boxes
- Octree Opacity (default 0.35): tone down line density
Also skip nodes without triangles, drop the per-depth HSL palette in
favour of a uniform cyan, and bump default Octree Max Depth to 8.
- Show Player Model: render the main character GLTF in camera-local
space so it stays visible at any pitch.
- Show Octree: overlay the collision octree as colored line segments,
one wireframe per spatial cell, colored by depth.
- Octree Max Depth: cap recursion to keep the scene readable.
