fix: wrap astro-llms-txt plugin to fix Windows path handling

The @4hse/astro-llms-txt plugin uses dir.pathname which returns
/C:/Users/... on Windows, causing doubled drive letters and file
not found errors. Inject a wrapper that uses fileURLToPath() to
normalize the path before passing it to the plugin.
