Make run, session, lock, and recovery transitions safe

Type: task Status: open

Question

Implement and fault-test a centralized AgentRun lifecycle that enforces one active project/provider/role/model session, serializes provider-cursor updates, preserves the ADR-0002 lock invariant across every database failure, applies a real wall deadline and renewable lease, reconciles every non-terminal state on startup/watchdog, and cannot let a second Hub process invalidate live work.
