Erik e5b2d15b63 fix(world): AP-48 client-side visibility cull (FPS sink across portal-hops)
acdream accumulated every CreateObject from every town visited and never pruned by
distance/time (only on server DeleteObject / respawn de-dup), so the entity tables +
the O(N^2) TickAnimations scan grew with each hop and sank FPS (confirmed in Release).

Faithful port of holtburger liveness.rs (ACE_DESTRUCTION_TIMEOUT_SECS=25,
CONSERVATIVE_VISIBILITY_DISTANCE_M=384): a world entity is evicted only after being
>384m AND outside the 3x3 landblock neighborhood for 25s continuous (arm-on-leave /
clear-on-return). Logic in a pure, unit-tested EntityVisibilityCuller; GameWindow
wires a 1Hz tick that snapshots the world entities + player and tears each evicted
guid down through the existing pruner. Player + held/equipped/contained items are
excluded (player by guid; inventory items never carry a world position so they never
enter the culled map). A re-created object starts fresh (deadline cleared on remove).
Skipped during a teleport hold (frozen player position). AD-32 registered.
