Add components/secrets/ (SPEC, realized shared-contract, code-verified
current-state for OtOpcUa/mxaccessgw/ScadaBridge, GAPS adoption backlog) and
register the Secrets row in CLAUDE.md + components/README.md. The
ZB.MOM.WW.Secrets lib is built + published 0.1.2 + reference-consumer-proven
(HistorianGateway, live vs the wonder historian); per-app adoption is the
tracked follow-on.
