jakman85andClaude Opus 4.8 08113ccfbb ci(l0): fix kyverno test expectations for CLI 1.13.4; pin kyverno-json 0.0.3
The offline `kyverno test` CLI cannot resolve the Flux postBuild token
${KYVERNO_VALIDATION_ACTION} in validationFailureAction, so the 4 policies
carrying it failed to load and their result rows reported "Not found" (14/17
cases). Render a throwaway copy of platform/kyverno with the base/prod value
(Enforce) before `kyverno test` in both ci/l0.sh and scripts/run-l0.sh; this
does not change in-cluster enforcement.

Add tests/values.yaml supplying Namespace labels so the offline CLI resolves
namespaceSelector matches -- without it the R-SEC-02/R-NET-05/R-IDP-02 Pod
cases were silently EXCLUDED (vacuous), not evaluated.

Pin kyverno-json 0.0.3 in ci/versions.env (0.0.5 has no upstream release;
0.0.3 is what run-l0.sh and the devcontainer already use).

# ci/l0.sh — Stage 2+3: ServiceDefinition schema validation + Kyverno L0 policy gate.
# Both run in CI WITHOUT a cluster (docs/14 §"Where each layer runs") — live now.
#
# Stage 2 schema : catalog/*.yaml validated against the ServiceDefinition
# schema (owner: T-0.3, schemas/).
# Stage 3 L0 : `kyverno test` over platform/kyverno/ — default-deny baseline
# present, no plaintext secrets, required labels/egress-class,
# ServiceDefinition schema conformance (owner: T-0.5, ADR-0011).
#
# Integration seams are env-overridable (see ci/lib.sh + README). When an owning
# subtree is still a placeholder, this reports SKIPPED (exit 3) for that sub-stage
# rather than a false pass — the gate then knows the seam is unwired, not green.
