New assets/shaders/ink_edge.gdshader: fullscreen depth+normal discontinuity
detection draws thin ink lines over the whole scene — the renderer-level
line pass anime-styled games use. Works on every model regardless of mesh
topology (kit buildings, cars, heroes, characters), with distance fade so
the skyline stays clean. Attached via LevelEnvironment so every map gets
it for whatever camera renders (first-person, third-person, spectator).
Street capture verified: crisp uniform outlines citywide, no artifacts.
