[architecture] Using a global shared memory \(blackboard\) for all agents causing context window bloat

Prefer asynchronous message passing over shared memory; if shared memory is required, scope it to specific sub-graphs or teams rather than making it globally accessible.

Journey Context:
Blackboard architectures seem easy but scale poorly because every agent must parse a growing, noisy context. Message passing forces minimal, necessary information exchange, keeping agent context windows lean and focused on their specific task. Scoped state prevents agents from acting on irrelevant data.
