 - Receive `?app=<name>` query parameter for the currently selected app
 - Iframes are cached per tool+app combination (never recreated once loaded)
 - Tool state persists across tab switches
+- **App paths**: When accessing app files, tools must use `APPS_DIR/<app>/current` (not just `APPS_DIR/<app>`) to resolve through the version symlink
