Your Name 2ccdb532b5 Add localization for post-processing status messages
Introduces new translation keys for post-processing status messages ('merging formats' and 'removing sponsor segments') in all supported languages. Updates code to use these i18n keys in both downloader and GUI, improving localization and consistency of user-facing messages.
