[synthesis] Parallel agents silently diverge in state because they read a shared resource at different times

Implement optimistic locking with version stamps on shared state reads; if a tool modifies shared state, the agent must re-read and validate the version before acting, or delegate to a serialized orchestrator.

Journey Context:
In multi-agent systems, agents are farmed out to handle subtasks. If Agent A and Agent B both read config.json, and A modifies it, B's internal representation of the state is now 'shadow state'—out of sync with reality. B proceeds to make decisions based on the old state. When B writes, it either overwrites A's changes or creates a logic bug. Standard agent loops assume read/write isolation, which doesn't exist in shared file systems without explicit concurrency control.
