Claude 5acb2c8ae4 surface.surface_cache_p3: review fixes (boundary edge uses on a split, planes, dispatch gaps) ...

- SubdivideNode: split into SurfaceCache::subdivide_node_split plus the base class
  ending; TrimSrfCache splits through its own subdivide_node, which re-implants a
  boundary parent's edge uses into the children with TrimSrfCache::implant_edgeuse
  (needs SmEdgeuse::GetUVTrimCurve: those cases defer on topology.edgeuse_p1; poly
  edges on query.poly) instead of dropping them through the base ImplantEdgeuse.
- trim_srf_cache shim and runner: ImplantEu prints every node of the tree (the
  children subdivisions make included); fixture implant_then_split_boundary_leaf.
- FFI accepts planes where it asked for a B-spline cache (an SmPlane is an
  SmBSplineSurface); the generator uses them; the tolerance test reads a plane's
  NURB through base_for_query (found by the new plane cases).
- DISPATCH GAP comments for GetTree's virtual BuildTree and SubdivideNode's GetTree;
  the bare-tree patch data reads (geom.tree, geom.grid, surface_p2) are dispatch
  gaps tagged with their owning units, not surface.surface_cache_p3.
- Stale docs and notes fixed; findings for the review points.

surface.surface_cache_p3: 445 pass, 0 fail, 155 deferred, --perturb 445/445.
surface.trim_srf_cache: 526 pass, 0 fail, 95 deferred, --perturb 526/526.
difftest --green: 117 units, 0 failed.
