Detailed Description

Per-tick collision-event queue.

Drained by gameplay code each tick; populated by the trigger subsystem (and, later, by the rigid-body contact solver in Phase 9).

The queue is thread-local on the write side (so parallel kernels that emit events don't contend), and merged into a single per-tick frontbuffer by beginTick(). Same architecture as physics::debug so determinism is preserved: events are written in entity-id order from a single thread, or merged after a sim step in stable iteration order.
