feat(physics): define deterministic flat collision assets

Browse source 
Add immutable indexed physics and containment BSP records, exact-bit polygon and Setup payloads, separated CellStruct/topology ownership, and iterative positive-before-negative flattening. Reject malformed graphs and ranges, and prove source identity over synthetic edge cases and installed retail DAT samples without cutting production traversal over.

replaced fresh per-resolve transition graphs and query temporaries with
reset-complete retained scratch: player, remote, projectile, camera, and
grounded walkable-publication profiles each measure 0 B/resolve, while
fresh-vs-reused output and body state remain bit-identical. I2 immutable flat
collision assets are the current execution point. Evidence:
fresh-vs-reused output and body state remain bit-identical. I2 now supplies
validated immutable flat collision records: synthetic and installed-DAT
source identity, exact float bits, deterministic pre-order, and corruption
tripwires pass without changing production traversal. I3 package
serialization and complete-catalog baking are the current execution point.
