Cleanup pass after the v1.4.3 cutover. Five files still carried gitea.com hosts or dead github.com security-advisory links because they were not touched in the prior URL sweep. - forge-announce.yml: Discord embed avatar and tag link - release-footer.md: custom-repo URL plus six doc/license links - bug_report.yml, config.yml, PULL_REQUEST_TEMPLATE.md: replace github.com/.../security/advisories/new with mailto:kontakt@ hellion-media.de. Gitea has no privately-reportable advisory feature; e-mail is the closest functional equivalent. Pure string replacement, no logic change.
