feat(vfx): port retail hidden and teleport presentation

 - **Missile/portal VFX campaign Step 6 implemented and independently reviewed 2026-07-14.** Pure Core now owns the retail projectile clock/integration/sweep primitive: 0.2-second catch-up quanta, 50-unit/second clamp, final-state acceleration, world-space omega, complete 3-D AlignPath, scaled Setup-local collision spheres, terrain/BSP/object continuous sweeps, exact `OBJECTINFO::missile_ignore`, self-shadow rejection, elastic/inelastic response, and correct full-cell rebasing across loaded landblocks. App live ownership and authoritative corrections remain Step 7. TS-2 is retired; ordinary missiles add PathClipped but not PerfectClip, so AP-83/AP-91 remain dormant.
 - **Missile/portal VFX campaign Step 7 implemented and independently reviewed 2026-07-14.** `ProjectileController` now attaches the Step 6 body to the canonical `LiveEntityRecord` after materialization and advances arrows, bolts, and spell missiles without another GUID map, renderer registration, or stale-spawn reconstruction. It commits predicted frames through `WorldEntity.SetPosition`, republishes static effect roots, and keeps collision shadows plus canonical full-cell buckets synchronized. A predicted crossing into an unloaded bucket suspends the body and shadow in that same quantum; pending/pickup residence retains the shadow registration for exact re-entry, and hydration plus the 96-unit retail activity gate restart at the current clock without backlog. Fresh State/Vector/Position/Movement packets correct or stop the same body after retail timestamp gates; SetState reaches the canonical body before optional projectile acquisition, and a non-finite local receipt clock cannot consume first classification. Removing Missile retains ordinary active-body physics (delegating to MovementManager when present), while both owners share the body and incarnation-scoped live-record cell. CreateObject vectors are installed only at body construction, never replayed by later SetState. Delete, reset, and GUID reuse use normal logical teardown; ACE remains authoritative for impact, damage, effects, and deletion.
+- **Missile/portal VFX campaign Step 8 implemented and independently reviewed 2026-07-14.** `LiveEntityRuntime` now distinguishes raw server PhysicsState from retail's side-effect-derived final state, beginning from constructor state `0x00400C08` and applying `set_state` in Lighting → NoDraw → Hidden order. `LiveEntityPresentationController` keeps Hidden objects logically alive while suppressing root mesh, collision, picking, radar, status, and new target acquisition; typed `PS_Hidden`/`PS_UnHide` plays remain DAT-driven, direct equipped children inherit NoDraw, particles/lights survive, and repeated/stale state cannot replay a transition. A normal visible CreateObject never fabricates UnHide. Effect-owner preparation is separate from pending F754/F755 replay so construction-state effects always run first. Remote fresh-teleport/cell-less placement now executes the exact ordered `teleport_hook` action bundle and a full-cell hard placement before contact/airborne routing, preventing an airborne correction from restoring the old location. Projectile Hidden state pauses the retained body without consuming its active identity or accumulating a clock backlog. TS-43 is retired; AP-69 remains because the separate 25-second/384-metre liveness cull is still unported.
