v1.1.1

Changed

• Internal code reorganization only — no behavior change and no change to the cleaner catalog
  (still 120 cleaners). The multi-class cleaner "bundle" files were split into one file per
  cleaner and grouped into per-tool folders, the DI composition root was split into
  per-category registration methods, and several CLI helpers (FileSystemService,
  ConsoleRenderer, CleanerApp) were simplified. The full test suite still passes.
