17 hours	feat(gpu): Add VignetteEffect and related files	skal
	- Implemented VignetteEffect, including its shader, parameters, and sequence integration. - Added VignetteEffect to demo_effects.h, shaders.cc/h, and asset definitions. - Updated seq_compiler to handle VignetteEffect parameters. - Added VignetteEffect to test suite and updated expected counts. - Ensured all changes build and tests pass. - Added vignette_effect.cc implementation file. - Updated CMakeLists.txt to include the new effect file. - Updated assets/demo.seq to include the VignetteEffect. - Updated assets/final/demo_assets.txt with the new shader asset.
6 days	fix: Resolve shader initialization crashes and build errors	skal
	Fixes crashes in demo64k and test_3d_render caused by uninitialized ShaderComposer. Moves InitShaderComposer() call before effect initialization in gpu.cc and adds explicit call in test_3d_render.cc. Also fixes include paths for generated assets.h in multiple files.
8 days	Refactor: Split demo effects and shaders into individual files	skal
	Split src/gpu/demo_effects.cc into individual .cc files for each effect and created separate files for post-processing helpers and WGSL shaders. Updated src/gpu/demo_effects.h to be a central header for all effect-related declarations and adjusted CMakeLists.txt accordingly.
