[architecture] Race conditions and corrupted shared state when multiple agents read/write a shared memory store concurrently

Implement an append-only event sourcing model for shared state, where agents read the current state but dispatch actions \(events\) to a central orchestrator that applies them sequentially, rather than allowing agents to mutate state directly.

Journey Context:
Multi-agent systems often use a shared scratchpad. If two agents read the same state, modify it based on an LLM output, and write it back, they overwrite each other's changes. Event sourcing ensures linearizability and provides a perfect audit log of inter-agent trust and actions. The tradeoff is increased complexity in reconstructing state from events and slower writes.
