jakman85andClaude Opus 5.5 04eb38584a fix(conformance): workload-mTLS certificates may use a private CA, if they prove they are workload-internal

R-TLS-01/docs/08 govern externally reachable TLS and ADR-0006 puts workload mTLS out of scope, but
tls-lifecycle-automated required ACME for every Certificate, which platform/buildkit's internal CA
cannot satisfy. Clause (5b) accepts the tls-scope=workload-mtls annotation only when the
certificate proves it: no Gateway serves it, internal names only, namespaced selfSigned/ca issuer
backed by an exempt CA certificate. Also fixes yamllint comma spacing in the buildkitd mounts.

jakman85andClaude Opus 5.5 f65c12b395 feat(images): build on rootless BuildKit over mTLS; verification moves into Containerfile verify stages
Operator decision on PR #81: no CI job may reach a privileged daemon. The act runner is untouched.

- platform/buildkit (+ clusters/base/buildkit.yaml): moby/buildkit v0.34.1-rootless pinned by
  digest, uid 1000, not privileged; caps drop ALL + SETUID/SETGID, seccomp/AppArmor Unconfined,
  read-only rootfs (each measured under podman). cert-manager CA + server/client certs, ClusterIP
  :1234, default-deny with ingress only from the act-runner pod (DinD masquerades jobs to it).
  No Kyverno exception: every applied policy matches app-namespace=true only.
- Each Containerfile names its shipped stage and ends in a `verify` stage holding every former
  `docker run` assertion (uid 65532, RUN --network=none, writable-path inventory standing in for
  the read-only rootfs). The old `&& echo` checks that could never fail are real assertions now.
- images.sh drives buildkitd with a pinned buildx (sha256-checked) via bake; PRs build verify
  targets with agent-runner FROM the in-run toolbox (target: context); main verifies, then pushes.
  Fails loudly when the builder secrets are absent or buildkitd is unreachable.
- infra/gitea/buildkit-client-secret.sh copies the client cert into Actions secrets.
