// Build script: compiles TypeScript extension sources to JavaScript using esbuild.
// The gi:// and resource:// specifiers are kept as external bare imports so GJS
// resolves them at runtime.  @girs/gnome-shell/* imports resolve through the
// package's dist/ shims which re-export from resource://, so after bundling the
// output only contains gi:// and resource:// references — no Node.js paths.
