- Extend the injected Background Jobs prompt guidance: system_notifications
push on completion, collect-only-when-idle wait protocol, and the graph
LLM-node collect-before-final-turn rule
- Mention the system_notifications push in the agent spawning guidance and
in the sisyphus/architect wait-protocol text (agent completions push
notifications too)
- config.example.yaml: max_concurrent_jobs (default 5, 0 = disabled)
- README: features-list entry pointing at the Background-Jobs wiki page
