Four new foreach blocks in GpuWorldState wire EntityScriptActivator
into the dat-hydration spawn/despawn paths:
- AddLandblock: fires OnCreate for each entity with ServerGuid==0
(live entities filtered out — they got OnCreate at AppendLiveEntity
and would double-fire on pending-bucket merges).
- AddEntitiesToExistingLandblock: fires OnCreate for each entity in
the promoted batch (all dat-hydrated by construction).
- RemoveLandblock: fires OnRemove(entity.Id) for each ServerGuid==0
entity before the loaded record is dropped.
- RemoveEntitiesFromLandblock: fires OnRemove for the demote-tier
entities about to be cleared (Near→Far demotion).
5 new integration tests cover the four fire-sites + the no-double-fire
invariant on pending-bucket merges. Pattern matches existing
GpuWorldStateTests (stub LandBlock heightmap + WorldEntity factory).
Closes#56 end-to-end. Slice A (per-part transforms in Tasks 1-3) +
Slice B (dat-hydrated entity DefaultScript firing, this task) both
ready for visual verification at Holtburg portal + Inn fireplace +
cottage chimney + spell cast.
Note: 8 pre-existing failures in Physics/Input/MotionInterpreter test
families are unrelated to this work (verified by re-running with this
task's changes stashed).
