[architecture] Letting agent mailboxes grow without bound

Apply backpressure: slow the producer, drop old messages, or use bounded queues so a slow agent cannot crash the whole system.

Journey Context:
When one agent is slower than its callers, its inbox grows until memory is exhausted or latency becomes unbounded. Buffering every message 'to be safe' is the opposite of safe. Backpressure propagates the slowdown upstream—either by blocking, dropping, or nack-ing—so the system stabilizes instead of accumulating debt.
