Leonid PershinandClaude Opus 4.8 79d406a9f4 Add 2D lightmap: occlusion shadows and point lights ...

Extend the Lighting module with a per-cell lightmap. LightmapBuilder (pure,
tested) fills an ambient base, shades occluder cells, and adds point lights
that attenuate with distance and are blocked by occluders between source and
cell (grid-traced soft shadows). Lightmap holds the grid plus a greyscale
texture (Upload) and a bilinear SampleAt for the simulation; a PointLight
component places lights in the world. LightmapSystem rebuilds the grid a few
times a second (ambient from the day/night cycle with a night floor, occluders
from a game-supplied grid, point lights from the ECS); LightmapRenderSystem
multiplies the lightmap over the world after the sprite flush and under the
HUD. Wired via scene.UseLighting(...), sampled through Lighting.SampleAt. Docs
updated.
