Detailed Description

Drains the arbiter at full rate (`ready` tied high, so the host can never
backpressure it) and counts delivered beats over a fixed cycle window. Holds
the tally on its report channel once the window closes.

Draining in hardware is the point: the host-driven tests are rate-limited by
the cosim DPI, so they cannot observe sustained throughput at all.
