Address review feedback on SOPS handling for encrypted values.yaml.
- renovate.json: Renovate has NO preUpgradeTasks option (verified against
the renovate-schema). Decrypt must therefore happen inside postUpgradeTasks
(which run after the tag bump, before the commit): decrypt the values.yaml,
then re-encrypt. Encrypting an already-encrypted file would double-encrypt
the existing ENC secret values. Only **/values.yaml is re-encrypted; the
docker-compose and Chart.yaml files are not SOPS-encrypted here.
- kubernetes/code/renovate: self-hosted Renovate runner as a Flux CronJob
running the renovatebot/renovate image, with sops allowed as a
postUpgradeTask command and the SOPS PGP key loaded to re-encrypt
values.yaml. Secrets come from SOPS-encrypted dotenv/env file sources.
- Wire code/renovate into the root kubernetes kustomization.
