 * @param pkgPath       Absolute path to the installed package directory, or null.
 *                      Used only for extra-file detection; not for content comparison.

 * @param selector      SelectorConfig controlling which package files are in scope.
 * @param marker        Managed file entries from the .filedist marker.
 * @returns CheckResult with missing, modified, and extra arrays.
