Subject: [PATCH 1/2] refactor: validate render-drift targets with kubeconform,
 not byte equality

The render-drift action compared each freshly rendered adapter file against
its committed counterpart with cmp, so any formatting, key-order, or comment
difference registered as drift even when the Kubernetes objects were
identical. Committed targets are now validated with kubeconform, reporting
drift only on genuine schema violations rather than byte-level noise.

Subject: [PATCH 2/2] fix: use semantic YAML comparison for render-drift, not
 schema validation

kubeconform validates that the committed target is well-formed Kubernetes
YAML; it does not compare the target against the freshly rendered output, so
genuine drift went undetected. The action now compares canonicalised YAML
(key order, formatting, and comments normalised) so real content drift is
reported while cosmetic differences are not.
