[architecture] No single agent owns an external resource, causing rate-limit thrashing and duplicate writes

Assign exactly one agent as the sole writer for each external resource; all other agents request mutations through a queue, and the owner serializes, deduplicates, and acknowledges every operation.

Journey Context:
When every agent can call the same API or write the same row, you get races, retries that double-post, and rate-limit exhaustion. Single-writer is the simplest consistency boundary: one agent orders all changes and can enforce idempotency keys. Read-only access can be broader, but writes need an owner.
