shader_build.zig is ShaderBuild.zig: a file that is a struct (its fields are the post chain's builds) takes a type's name

The naming the split agreed on: a file with fields is a type, TitleCase, as Messages.zig and Layer.zig are. Its importers bind it as ShaderBuild; comments and docs/render-pipeline.md name the new file. No behaviour changes.
