fix: Resolve shader initialization crashes and build errors

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.
