Replaces the 2D-only demo pipeline with a 3D cell-based blobber generator. Per-cell face walls, per-material mesh emission, and a GDExtension binding that returns a Dictionary with ArrayMesh surfaces the demo consumes directly. - src/blobber/: cell3d_t data model, dungeon container, pipeline that wraps the 2D generator per level and materializes into cell3d - src/mesh/: face-quad emitter with per-material groups + .obj dump - src/genesis3d_main.c: new CLI driving the blobber + mesh - godot/: BrogueGen.generate_dungeon(seed, num_levels, depth) binding with dungeon_to_dict packing cells + mesh surfaces - demo/: demo_blobber.tscn + dungeon_builder.gd, func_godot addon for the .map export path, point/entity templates, TrenchBroom docs - Retired: old arcade/FPS demo scenes and their scripts, unused meshlib Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
