jakman85andClaude Opus 5.5 d2c4bd5194 fix(buildkit): allow buildkitd egress to Gitea's backend so the Gateway stops 403ing the push
gate / gate (pull_request) Successful in 1m56s
gate / conformance (pull_request) Has been skipped
Images run 337's push failed with "403 Forbidden: Access denied". Measured
read-only: Gitea never logged the request; an unauthenticated GET /v2/ via the
Gateway gets 401 from Gitea when sent from act-runner (egress unrestricted) but
403 from buildkitd; Hubble logs it as an L7 http-request DROPPED with
traffic_direction EGRESS. Cilium >= 1.16.8 (CVE-2025-30162) re-checks the
source pod's egress against the proxied backend identity, and buildkitd's
egress only allowed world and the ingress entity. Same fix as 68690e5 for
Keycloak. Gitea's ingress already admits reserved:ingress and is unchanged.

jakman85andClaude Opus 5.5 04eb38584a fix(conformance): workload-mTLS certificates may use a private CA, if they prove they are workload-internal
gate / gate (pull_request) Successful in 1m58s
images / images (pull_request) Failing after 7s
gate / conformance (pull_request) Has been skipped
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.
