Pointmap: trimesh→.glb (MoGe-2 pattern), Model3D back, cap input height to 1024

Pointmap: bring back .ply + Model3D, but native-res only (max 1024×768 grid → 200K pts)

Pointmap: pivot to depth-z heatmap (turbo); drop Model3D + Open3D + .ply pipeline

Bump to gradio 6.13.0 + unpin huggingface_hub

Pin huggingface_hub<1.0 (gradio 5.6 still imports HfFolder)

Bump to gradio 5.6.0 (modern, fixes schema bool bug)
