wip(L28): passage columns/routes culled per tile (BVH); cost back near L24, bit-identical to L27

GenerateMesh scopes passage queries to the tile's sample bounds with a feature AABB BVH plus
per-passage segment BVHs; L9 proof boxes use a passage-bound BVH. Whole view vs L24: FI ~0%, SW
+3.7% (reviewer interleaved). All hashes equal L27; all passage/route/proof audits pass.
