build: baked lighting pass on kit_demo test map
Restructured kit_demo.tscn from linear demo to enclosed 5.12x5.12 room:
- 2x2 floor tiles, 8 wall segments (including doorway + window)
- Pillar at room center, beam overhead, accent panels
- West/east walls rotated 90° Y for proper enclosure
Lighting infrastructure:
- WorldEnvironment with ambient light
- DirectionalLight3D (sun key light, 45° angle, shadows enabled)
- OmniLight3D (warm interior fill light)
- ReflectionProbe (box projection, room-sized extents)
- LightmapGI (Quality=High, bounces=3, denoiser=true)
- Tool script prints bake status in editor
Scripts:
- bake_lighting.gd: validates LightmapGI config from CLI
- validate_scene.gd: full scene validation (17 checks, all pass)
Note: Godot 4.7 removed LightmapGI.bake() from runtime API.
Baking must be done in the editor: select LightmapGI node > Bake Lightmap.
