fix(loop): eliminate main chat saturation from sidechat activity

- Exclude automated jobs ([JOB ...]) and heartbeat from sidechat activity digestion
- Exclude recurring background job channels (box-*-health, canary, heartbeat) from monitored sidechats
- Reset default prompt destinations to dedicated task sidechats (646 tasks, main-loop brain, pip tasks, muse tasks)
- Prevent synthetic 'Incoming sidechat activity' prompts from polluting agent Main Chats
