/* Rebuild every esbuild bundle the tests load, so a test run can never exercise
   a stale bundle. `npm test` calls this first; run it standalone when you only
   want fresh bundles.

   The aliases live here (and nowhere else) so every bundle resolves `electron`
   and `@shared` the same way. A bundle built without
   `--alias:@shared=./src/shared` does not even compile: pty.ts reaches
   @shared/theme through settingsStore.ts -> windowChrome.ts.
