[architecture] Race conditions and lost updates when multiple agents read and write to the same shared state concurrently

Implement the Single-Writer Principle \(Actor Model\): assign unambiguous ownership of state variables to exactly one agent. Other agents must request mutations via messages rather than writing directly.

Journey Context:
Developers often expose a global key-value store to all agents, assuming atomic reads/writes. However, if Agent A and Agent B read a value, decide based on it, and write back, the last write wins, losing A's update. The Actor Model solves this by encapsulating state within the agent that owns it, serializing updates through its message queue, and eliminating concurrent write anomalies.
