Captures the runtime-monitoring side of the 2026-05-28 silent-empty-
registry incident retrospective. Pairs with backend commit 28b17f2
(CI typecheck gate). Defines the proposed Gatus probe set, the
/api/health endpoint that has to land first, and a follow-up issue
list. Includes a retrospective table showing what this would have
caught across recent incidents.
