[architecture] State corruption when agents share and overwrite a global context dictionary

Use immutable state snapshots or append-only logs for inter-agent context, combined with scoped context variables rather than a single mutable global state.

Journey Context:
Passing a single mutable dictionary \(like a global context\_variables dict\) between agents seems easy but leads to state corruption. Agent A updates a key, Agent B overwrites it, and Agent A's context is lost. Instead, treat agent state like event sourcing: use append-only logs for actions, and pass immutable snapshots or scoped variables to specific agents. If an agent needs to modify shared state, it should emit a structured event that a central state manager processes, ensuring a single source of truth.
