[architecture] Multiple agents modifying the same shared state causing race conditions and overwrites

Implement unambiguous single-agent resource ownership. State can be read by many, but written only by the owning agent. Use a central state graph with deterministic reducer functions for state mutations.

Journey Context:
In distributed LLM systems, concurrent writes cause data loss. Agent A and Agent B might both try to update a user's profile simultaneously. Developers often try basic locks, but LLM latency makes locks deadlock-prone. The architectural fix is to avoid concurrent writes entirely by assigning strict ownership of state domains to specific agents, or using a central 'Supervisor' agent that serializes all state mutations via a defined schema.
