1. Slope clipping: replaced single foot-forward Z sample with 4-point
sampling (forward, back, left, right at 0.7 units). Takes the max Z
across all samples so both uphill and downhill slopes keep feet above
the terrain mesh surface. Removed the +0.1 Z bias entirely.
2. Player culling: replaced per-entity scan (alwaysVisibleEntityId) with
per-landblock skip (neverCullLandblockId). The player's current
landblock is computed from _playerController.Position and passed to
the renderer. Simpler, faster, and more reliable.

Three user-reported movement fixes:
1. Player disappears when facing away: StaticMeshRenderer now accepts
an alwaysVisibleEntityId. When a culled landblock contains the
player entity, it is still drawn. Prevents the frustum culler from
hiding the player character when they walk far from their spawn
landblock.
2. Jump too high: JumpImpulse reduced from 10.0 to 3.5 (placeholder;
retail scales by Jump skill value from the server).
3. Slope Z alignment: replaced the frame-delta slope bias with a
foot-forward sampling approach — sample terrain Z at 1 unit ahead
in the walk direction and use max(center, foot) as the ground Z.
Handles multi-grade slopes where the terrain rises faster than a
single-point sample tracks.

Four targeted fixes for user-reported movement/visual bugs:
1. Player entity disappearing: GpuWorldState now supports persistent
entities (MarkPersistent/DrainRescued). The player character survives
landblock unloads and gets re-injected into the streaming window at
the current center landblock.
2. Feet sinking into terrain: +0.15 Z bias in PlayerMovementController
keeps the character model above terrain z-fighting edge cases.
3. Camera after portal teleport: ChaseCamera.Update now called
immediately after teleport snap so the camera recenters on the new
position instead of lingering at the pre-teleport location.
4. Scenery on roads: SceneryGenerator now checks road status at the
final displaced position (not just the origin vertex), catching
objects that drift from non-road vertices onto road cells.

Per-frame controller that reads MovementInput (WASD/ZX/Shift/mouse),
drives PhysicsEngine.Resolve for collision, and tracks motion state
changes for outbound server messages + animation switching. Walk
(~4 u/s) and run (~7 u/s) speeds match AC retail. Heartbeat timer
triggers AutonomousPosition every ~200ms while moving.
5 new tests covering idle, forward, run, turn, and state-change
detection.
