Subject: fix(shaders): deduplicate VertexOutput/vs_main via
 render/fullscreen_uv_vs snippet

- Fix vs_main return type (VertexOutput, not vec4<f32>)
- Fix #include paths in passthrough, gaussian_blur, heptagon, combined_postprocess
- ShaderComposer: assert + suggest correct path on missing #include (non-STRIP_ALL)
- VerifyIncludes: upgrade WARNING to ERROR + assert, add "did you mean?" hint
