v0.7.0: bone weight preservation, multi-mesh viewer, clean pipeline fix

- Add --preserve-weights flag to simplify, voxel, and clean commands
  that transfers bone weights from input to output via nearest-vertex
  lookup, preserving JOINTS_0/WEIGHTS_0/skin/animations in GLB output
- Extend GLB writer with full skin data support: joint nodes, inverse
  bind matrices, per-vertex joint indices and weights, animation clips
- Viewer: default to first mesh when GLB has multiple meshes instead of
  erroring; N/P keys to cycle through meshes; show mesh name in UI
- Fix clean pipeline: simplify voxel output even with small holes
  instead of falling back to direct QEM on the original non-manifold mesh
- Suppress baby_shark panic output during catch_unwind fallback paths
