v1.1.1 - Room Chat and File Timeline

See teammates coordinate and exactly what each one touched.

Added

• Room Chat feed in the inspector Channel tab: live per-room view of inter-agent messages (who said what to whom).
• File Timeline per agent in the Work tab: every file each teammate created, edited, or deleted, with the originating task.
• AgentMailbox keeps the last 200 messages per room so squad chatter replays across reloads.

Validation

• npm run typecheck - pass
• npm run build - pass
• npm run package:vsix - pass
