/**
 * Crossref Diagnostics Capability.
 *
 * Keyless bounded probe (DESIGN D2 round-3 ruling): doctor probes
 * every always-configured science supplier, so the Crossref probe is
 * ONE minimal keyless wire call on the works endpoint — still one
 * call, still `rows=1`, but it exercises the SEARCH capability
 * (`query=scoutline-doctor-probe`). #163: a bare works list can stay green while the
 * search surface degrades, so a works-list-only probe reports
 * capability health it never tested. Red on a degraded search is
 * INTENDED — the row reports the search capability, not bare
 * connectivity. The politeness posture applies to it too: the
 * house UA carrying the mailto contact. When `diagOptions.probe` is
 * false, `invoke` resolves immediately without touching the network.
