/**
 * Install-time deployer for plugin-supplied native UE modules.
 *
 * A plugin declares `nativeModule:` in ue-mcp.plugin.yml with a `source:`
 * directory inside its npm tarball. On install we copy that directory to
 * `<projectDir>/Plugins/<uePluginName>/` and record every copied file so
 * uninstall can clean up without nuking user edits.
 *
 * The tracking file lives at `<projectDir>/.ue-mcp/native-modules.json`:
 *
 *   {
 *     "<npm-package-name>": {
 *       "uePluginName": "PIE_Studio",
 *       "pluginVersion": "0.0.2",
 *       "installedAt": "2026-05-26T00:00:00.000Z",
 *       "files": ["Plugins/PIE_Studio/...", ...]   // relative to projectDir
 *     }
 *   }
