feat(net): port retail physics spawn and event timestamps

Browse source 
Parse the complete PhysicsDesc plus F754/F755 packets, correct every PhysicsState bit, and gate all nine retail update channels with generation-safe immutable snapshots. Preserve ForcePosition, teleport, placement, velocity, parent, pickup, delete, and same-generation CreateObject ordering from the named client.

Separate accepted logical lifecycle notifications from retained UI qualities, make GUID replacement and session reset clear every projection exactly once, and add packet, wraparound, malformed-input, parent FIFO, canonical-position, reconnect, and GUID-reuse conformance coverage.

Until then, the parallel-dicts problem is bounded inside one class
instead of spread across `GameWindow`.
`InboundPhysicsStateController` is the first shipped slice of that boundary:
it owns the nine-channel retail timestamp gates and the latest accepted
immutable CreateObject snapshot. It deliberately owns no renderer adapter,
local entity ID, physics body, animation, effect, or spatial bucket; those
move together in the `LiveEntityRuntime` extraction.
`ParentAttachmentState` is a focused interim pending queue for ParentEvent:
it keys unresolved relations by child and parent generation, distinguishes
atomic incarnation replacement from true deletion, and migrates into
`LiveEntityRuntime` with the general mixed packet queue.
