The operator ruled the implementation repo's main (50c8719) the latest
and accepted state. Sync the spec to it.
Accepted changes are reflected: one bare-metal environment, TrueNAS bulk
storage, R2 off-cluster backup, CloudNativePG, single-node VPN gateway
with Cilium fail-closed, inbound WireGuard, per-app auth sidecars,
Renovate, the CI gate as approver, and the pm-agent. New ADR-0017..0025;
ADR-0016 corrected and accepted; R-* IDs unchanged, eight amended.
Where the implementation has simply not met a requirement, the
requirement stands and the shortfall is recorded in docs/16-known-gaps.md.
