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.

The G5 profile's 22.34 KiB/frame remainder led into Slice I1. That slice is
now complete: player, remote, projectile, camera, and grounded
walkable-publication profiles each measure 0 B/resolve, with bit-identical
fresh-vs-reused results and complete reset/reentrancy gates.
fresh-vs-reused results and complete reset/reentrancy gates. Slice I2 is also
complete: immutable physics/containment BSP, polygon, Setup, bounds, and
EnvCell-topology records preserve source float bits and ordering across
synthetic corruption gates and representative installed DATs without changing
production traversal.
Slice H's retained UI/frame, bounded-light, and pooled/borrowed/direct network
work is complete; the exact seven-checkpoint connected lifecycle/reconnect gate
passes. Slice I is active at I2 from
