/**
 * Gateway smoke test.
 *
 * Exercises the full dispatch path through the deterministic `mock` connector:
 *   - `stream("mock-1", …)` emits text deltas, a tool call, then a terminal
 *     `done` carrying the folded reply;
 *   - `complete("mock-1", …)` resolves a `tool_calls` reply with non-empty
 *     blocks;
 *   - `estimateCost` returns a finite number for a card + usage pair.
 *
 * No network, no credentials — the mock card/connector make the routing wholly
 * deterministic.
