[frontier] Flat multi-agent topologies create N-squared communication chaos and no clear accountability

Adopt hierarchical multi-agent teams with Manager-Worker-Reviewer topology: Manager decomposes tasks, delegates to Workers, then Reviewer verifies results before Manager aggregates. Use a shared state store for task status visibility.

Journey Context:
Flat agent swarms \(like early AutoGen\) suffer from broadcast storms where every agent talks to every other, and conflicting edits overwrite each other. Hierarchical teams with explicit review stages mirror software engineering workflows \(design → code → review\). This topology is winning in production for complex tasks like code generation where verification is critical, preventing the 'too many cooks' problem of flat hierarchies.
