Report #40052

[architecture] Agents duplicate effort or miss prior discoveries because they only read their own private context

Use a 'Blackboard' architecture where a shared structured state object is updated and read by all agents, rather than passing full conversation histories.

Journey Context:
Passing full chat histories between agents is token-inefficient and leads to distraction. A shared blackboard allows agents to read only the relevant state variables they need. Tradeoff: Requires defining the state schema upfront; agents might ignore the blackboard if not prompted to check it.
