- Group.forgeLabel (default off, editable per group in the console) shows the
source forge on every message the group's routes dispatch
- Discord embed footer: forge name next to the repo + the site's favicon as
icon_url (Gitea instance's own favicon from its origin)
- Telegram footer: hyperlinked site name (GitHub or Gitea hostname); custom
webhooks render a plain 'Custom' label
- forgeInfo() derives branding from event.provider + repository.html_url;
dispatch attaches it to the NeutralMessage like mentionRoleIds
- validateGroups accepts forgeLabel booleans; GroupEditor gains the toggle
- tests: forgeInfo unit, discord/telegram footer render, dispatch on/off
- docs: groups.md + message-format.md (en/zh), config.example.yaml, AGENTS.md
- fix: wrangler.jsonc compatibility_date was an incomplete '2026-'
