[architecture] Centralized orchestrator agent becomes a sequential bottleneck in concurrent workflows

Implement a decentralized or event-driven architecture where agents can subscribe to events and act independently, or use a lightweight deterministic state machine as the orchestrator instead of an LLM.

Journey Context:
Putting an LLM in the middle of a loop to decide what happens next after every single agent action creates a massive bottleneck. The LLM takes seconds per turn, making parallel tasks run sequentially. Replacing the LLM orchestrator with a deterministic state machine \(like a DAG or finite state machine\) allows parallel fan-out and fan-in, keeping the LLMs only on the execution nodes.
