[frontier] Agents in a swarm overwriting each other's work due to lack of coordination

Implement a 'Manager-Worker' topology using a centralized 'state monolith' \(single source of truth\) where a Manager agent maintains a 'task board' \(locked tasks, completed tasks, dependencies\) and Workers check out tasks with pessimistic locking \(checkout expires after timeout\).

Journey Context:
Early multi-agent systems used 'group chat' patterns where all agents saw all messages, leading to race conditions when two agents picked the same task. The breakthrough is recognizing that agent swarms need database-style transaction semantics. The Manager acts like a scheduler/OS, maintaining a conflict-free replicated data type \(CRDT\) or simple locked-task list. Workers must 'checkout' tasks \(pessimistic locking\) rather than optimistically assuming availability. This differs from pure message-passing \(A2A\) by enforcing a strict hierarchy that prevents circular waits and priority inversion.
