15 hours	chore: Update documentation, generated assets, and cleanup	skal
	Removed obsolete scene_query.wgsl (replaced by variants). Updated TODO.md. Committed generated asset files reflecting new shader snippets.
15 hours	refactor(gpu): Implement compile-time BVH toggle via shader composition	skal
	Completed Task #18-B optimization and refactoring. - Replaced runtime branching in shader with compile-time snippet substitution in ShaderComposer. - Added 'scene_query_bvh.wgsl' and 'scene_query_linear.wgsl' as distinct snippets. - Refactored Renderer3D to manage two separate pipelines (with and without BVH). - Updated ShaderComposer to support snippet substitution during composition. - Verified both paths with test_3d_render (default and --no-bvh). - Removed temporary shader hacks and cleaned up renderer_3d.wgsl.
16 hours	feat(perf): Add toggle for GPU BVH and fix fallback	skal
	Completed Task #18-B. - Implemented GPU-side BVH traversal for scene queries, improving performance. - Added a --no-bvh command-line flag to disable the feature for debugging and performance comparison. - Fixed a shader compilation issue where the non-BVH fallback path failed to render objects.
2 days	feat(gpu): Implement recursive WGSL composition and modularize shaders (Task ↵	skal
	#50) - Updated ShaderComposer to support recursive #include "snippet_name" with cycle detection. - Extracted granular WGSL snippets: math/sdf_shapes, math/sdf_utils, render/shadows, render/scene_query, render/lighting_utils. - Refactored Renderer3D to use #include in shaders, simplifying C++ dependency lists. - Fixed WGPUShaderSourceWGSL usage on macOS to correctly handle composed shader strings. - Added comprehensive unit tests for recursive composition in test_shader_composer. - Verified system stability with test_3d_render and full test suite. - Marked Task #50 as recurrent for future code hygiene.
