Added a dedicated Configuration backup section in Settings.

Export website rules, filename rules, ChatGPT folder settings, language and rule order to a JSON file. Importing validates the file and loads it into the form for review before you save. Consent decisions and download activity are not included.

No new permissions. Existing settings remain unchanged until the user saves imported settings.

Updated Windows Support download link to Support 1.2.6. Support now uses a shared AutoConfig dispatcher and can be installed alone or alongside Firefox Enhancements 0.1.18 in either order. Migration includes ownership checks, backups and rollback. Routing rules, permissions, extension ID and stored settings remain unchanged. Windows Support must be installed separately; close Firefox first.
