// P5.4 — the `on_build` override. A user `#run on_build(build);` replaces the
// stdlib `default_pipeline` as the build driver; the compiler invokes it after
// codegen with the `BuildOptions` handle. This build GROWS a `List` on the build
// VM (comptime List growth works only on the VM — issue 0141; the legacy interp
// fails it) then DELEGATES to `default_pipeline` for the real emit + link, so a
// working binary is still produced → "runtime main".
