Part of #1205.

(#13) Region map capture: a perfect orthographic top-down render of the region (max LOD), used as the minimap / world map background and shareable. Needs the stage 1 ortho camera.
(#23) Snapshot avatar matte and selection, 90-degree portrait, local snapshot panel. Fits Photo Studio.
(#16) Instant replay:
- a ring buffer of the last N seconds, encoded on the GPU's video encoder (VK_KHR_video_encode), saves an MP4;
- gated on device caps;
- the ring is budgeted under our RAM / VRAM rules (no unbounded growth).
(#12) Minimap overhaul:
- rotating, whole-region view, physical-only, terrain background, compass styles;
- marks and zones (pins, rectangles, circles, polygons);
- SLURL copy.
(#18) Selection outline styles (classic silhouettes, GPU outline / wireframe). Settle on as few styles as make sense.

For every stage:

Port by hand onto current dev. Their base is 44+ commits behind, and the renderer files have moved on.
Strip their settings down to the few that earn a place (minimal config space). Experiment toggles are Persist=0.
Never take their custom SDL3 build (SDL3-3.4.18-gmdx1), updater, crash reporter, installer or branding.
