[synthesis] Multi-agent handoffs cause overwrites due to stale file system views

Implement optimistic locking or version stamps on files. Before an agent writes to a file, it must verify the file's current hash matches the hash it read prior to modification.

Journey Context:
In multi-agent systems, Agent A reads config.yaml, modifies it in memory, and passes to Agent B. Meanwhile, Agent C also modified config.yaml. Agent B writes its changes based on the stale version, erasing Agent C's work. This is a classic distributed systems race condition, but agent frameworks rarely expose file locks because agents operate in isolated memory spaces. Treating the filesystem as a shared database with Multi-Version Concurrency Control \(MVCC\) prevents silent data loss during handoffs.
