This pull request adjusts the polyfill bundling process. A new isLocalFile helper function is introduced to determine if a polyfill entry is a local file path. When a local file is detected among the polyfills, external package resolution is disabled for the polyfills bundle. This forces all polyfills, whether local or from packages, to be bundled together, which preserves their specified execution order. When no local files are in the polyfills list, the behavior respects the configured externalPackages option.

… local files are present The polyfills bundle now conditionally employs external package resolution only if no local files are detected in the polyfills array. If local files are present, all polyfills are bundled together to ensure the import execution order is correctly preserved between local and package-based entries.
