fix: honor /new resets with mentions in groups

CHANGELOG.md

@@ -15,6 +15,7 @@
 - Group chats now honor `inbound.groupChat.requireMention=false` as the default activation when no per-group override exists.
 - Gateway auth no longer supports PAM/system mode; use token or shared password.
 - Tailscale Funnel now requires password auth (no token-only public exposure).
+- Group `/new` resets now work with @mentions so activation guidance appears on fresh sessions.
 - Canvas defaults/A2UI auto-nav aligned; debug status overlay centered; redundant await removed in `CanvasManager`.
 - Gateway launchd loop fixed by removing redundant `kickstart -k`.
 - CLI now hints when Peekaboo is unauthorized.
