Adds the family backlog standard to the root index (open work = Gitea issues,
shared label set, BTDB excluded) and converts components/*/GAPS, hosted-lib
CLAUDE.md notes, code-reviews, infra/glauth and plan docs to banner + issue
pointers (scadaproj #5-#19, ScadaBridge#79).
All 3 apps adopted on branch feat/adopt-zb-telemetry (behaviour-preserving).
Records the per-repo result + accepted scope deviations (ScadaBridge keeps
LoggerConfigurationFactory + TraceContextEnricher instead of AddZbSerilog;
MxGateway keeps GatewayLogScope, exposes redaction via ILogRedactor seam) and
deferred follow-ons (#6 ms->s, #7 meter rename, #9 app instruments, OTLP, and
the new ScadaBridge Site-node HTTP/1.1 metrics-listener item). Corrects the
prior false 'MxGateway logging adopted on its own branch' claim — that migration
actually landed in this pass.
