New GameplayRenderer extends Node2D with built-in occlusion support.
Subclasses override _gameplay_process() and _gameplay_draw() instead
of _process() and _draw() — these are skipped when a fullscreen
implant app covers gameplay.
Migrated all 5 gameplay renderers:
- CursorRenderer: hover detection + bracket drawing paused
- EntityRenderer: position lerping paused
- FogEntities: fog dot rendering paused
- SoundIndicatorRenderer: directional arrows paused
- WorldRenderer: tile/fog/entity updates paused
No more manual occlusion wiring — the base class handles everything.

Fog entity cognitive delay rendering (D-059/D-060): sonar-style sound
pings (3 concentric rings, 1.5s fade), unrecognized grey blobs with
breathing pulse, D-033 color transition at 50% recognition progress,
±0.5 tile position drift. FogEntities node at z:950 between fog
shader and InsertOverlay.
Protocol v7 bump to match server PR #23 (pending_recognitions field).
Wires dialogue box and fog entities into game loop with mock test data.
