♻️ refactor(architecture): eliminate production cycles

[zrr1999]

Summary

• reduce production circular dependencies from 75 edges / 10 SCCs to 0 / 0
• extract ownership contracts across daemon and Cockpit/TUI coordination, AI and ask routing, extension background/drive state, and role runtime clusters
• enforce a global production-cycle prohibition in dependency-cruiser and hygiene ratchets
• preserve existing public APIs, daemon command behavior, session lifecycle, runtime control, and transport semantics while moving implementation ownership behind explicit contracts
