[architecture] Race conditions and state corruption when agents share resources

Implement unambiguous resource ownership where only one agent owns a specific state key or file, or use append-only state reducers to prevent concurrent write conflicts.

Journey Context:
In multi-agent systems, if Agent A and Agent B both read a file, modify it, and write it back, last-write-wins causes lost updates. Unlike traditional threading, you can't just use standard mutexes easily across distributed LLM calls. The solution is architectural: assign exclusive write ownership to a single agent for specific state partitions, or use a transactional state graph where updates are append-only or defined via custom reducer functions.
