Parse @agentname patterns in channel message body. Mentioned agents (who are channel members, excluding sender) get mention=true flag in their inbox notification metadata. Channel message metadata includes mentioned_agents list for all recipients. - mentions.go: regex parser with email exclusion, dedup, 22 test cases - BroadcastMessage: metadata now uses json.Marshal, includes mentions - Tests verify mention flag, self-mention exclusion, non-member skip Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
