Subject: refactor: Deduplicate CommonUniforms with #include in WGSL shaders

Replace redundant CommonUniforms struct definitions across 13 shaders
with #include "common_uniforms" directive. Integrate ShaderComposer
preprocessing into all shader creation pipelines.

Changes:
- Replace 9-line CommonUniforms definitions with single #include line
- Add ShaderComposer.Compose() to create_post_process_pipeline()
- Add ShaderComposer.Compose() to gpu_create_render_pass()
- Add ShaderComposer.Compose() to gpu_create_compute_pass()
- Add InitShaderComposer() calls to test_effect_base and test_demo_effects
- Update test_shader_compilation to compose shaders before validation

Net reduction: 83 lines of duplicate code eliminated
All 35 tests passing (100%)
