[synthesis] Concurrent Agent Writes to Shared Config Cause Silent State Overwrites

Implement optimistic concurrency control \(e.g., ETags or version numbers\) on shared state files, forcing agents to merge or fail explicitly rather than silently overwriting.

Journey Context:
Two sub-agents read a shared configuration file, modify different keys in memory, and write back concurrently. The last write wins, silently erasing the first agent's modifications. The system proceeds with partial configuration, leading to unpredictable and untraceable catastrophic failures. The synthesis is applying database concurrency control to agent file system interactions: agents treat the file system as a communication channel, but without locking or versioning, it acts like a lost-update anomaly. File writes must be treated as transactions, not just output dumps.
