[architecture] Agent teams silently corrupt shared state because multiple agents update the same record

Assign exactly one agent as the owner of every mutable resource; all other agents send mutation requests to the owner rather than updating the resource directly.

Journey Context:
The natural first design is a shared state object every agent can read and write, which works in demos and fails in production the moment two agents interleave reads and writes or one rolls back an update. Locking is possible but couples agents to a global coordinator and adds deadlock risk. Actor-model ownership eliminates the ambiguity: each resource lives in one agent's local state, changes are serialized through that agent's inbox, and other agents reference immutable snapshots or request mutations. This is the pattern behind Orleans virtual actors and Erlang/Elixir processes, and it maps cleanly to LLM agents where, for example, one agent owns a ticket while another owns a user profile.
