Thanks! Before merging, please keep the SnippetsLab product name unchanged, use Finder rather than Explorer for inFinder, and fix the visible French errors such as applicquer, Défault, and URL Décode.

Hello @antonreshetov,
I have fixed the conflicts.

Thanks for updating the French translations! There is one issue to fix before this can be merged: src/main/i18n/locales/fr_FR/messages.json is no longer valid JSON.

• The closing }, for the empty error object was removed before description. Please restore it so description remains a top-level key.
• There is a trailing comma after description.language. Please remove it.

This prevents the French messages namespace from loading, including the existing confirmation and warning translations. I checked all five changed JSON files; the other four parse successfully.

Please also rename the PR to follow Conventional Commits, for example: fix(i18n): update French translations.
