- forgejo/server-config/ifcurl-preview.service: systemd unit for the preview
service with dedicated user, EnvironmentFile for cache config, and
--allowed-hosts in ExecStart
- forgejo/server-config/gitconfig-ifcmerge: registers two [merge] driver
variants (ifcmerge and ifcmerge_ours) for the asymmetric .ifc merge case
- forgejo/README.md: systemd deployment section (manual + service), ifcmerge
section covering Perl script install, driver registration, per-repo
gitattributes, and merge-direction constraint (merge-commit preserves main's IDs)
- README.md: remove stale "IFC file proxy" description; update quick-summary
to show systemd install path
