feat(physics): port retail complete object frame pipeline

Restore the named-retail object update order across local, remote, static, projectile, animation, shadow, teleport, and effect lifetimes. Separate authoritative root commits from spatial rebucketing, preserve per-owner hook/FIFO ordering, and remove update-path allocations with exact lifecycle and residency gates.

Add deterministic conformance, adversarial lifetime, GUID-reuse, pending-cell, quaternion, timestamp, and allocation coverage. Release build is warning-free and all 6,446 tests pass with five intentional skips; retail, architecture, and adversarial reviews are clean.
