PDF Image Merger 1.0.1

New

• Localization: PDFImageMerger now speaks English, Italian, Spanish,
  French, Chinese (Simplified), and Hindi. It follows your OS language on
  first launch — open Preferences (gear icon, top right) to pick one
  explicitly, or to set the theme (Automatic/Light/Dark) instead.

Fixed

• Language and theme preferences did not actually survive an app restart.
  pywebview runs its underlying webview in a private/ephemeral mode by
  default on every backend, which never writes localStorage to disk —
  so a preference saved there was silently gone on the next launch.
  Preferences now live in their own JSON config file instead (see the
  README's Localization section for the
  exact path per OS).
• Linux: a ModuleNotFoundError: No module named 'gi' traceback appeared
  in the console on every launch. pywebview probes for a GTK backend
  before falling back to Qt unless told otherwise; the app now skips that
  probe entirely when PyQt6 is available (which is the default install —
  see requirements.txt), instead of just tolerating the noise.
• The "Don't modify images" toggle switch never actually changed color
  when turned on — Franken UI's toggle component needs an explicit
  uk-toggle-switch-primary modifier class for that; it was missing.

Under the hood

• The handful of user-facing strings the Python backend itself generates
  (build errors, native file-dialog filters) now come from the same
  translation catalog as the UI, instead of being hardcoded in Italian.
