I added the most requested features to the plugin in a branch

main ← feature/group-category-restrictions

approved 03:50PM - 20 Feb 26 UTC

## Summary - Group-based restriction (`signatures_allowed_groups`) — server-side… enforced - Category-based display (`signatures_show_in_categories`) - First-post-only mode (`signatures_first_post_only`) - Signature length cap (`signatures_max_length`) and image height limit (`signatures_max_image_height`) - URL validation hardened to HTTP/HTTPS only, max length reduced to 2048 All defaults are backward-compatible.

If y’all can give this branch a run and give feedback I can merge it next week.
