cloudkit-schema-source-of-truth skillA

cloudkit-schema-source-of-truth is agent-read markdown (skill) from wei18/apple-dev-skills: Use when a CloudKit-backed app's persistence layer adds or edits a record type, field, or index and the schema needs to reach a container, or when asked "how do I push CloudKit schema to Production", "why can't cktool deploy to prod", or "why is a field silently missing in Production". Covers one committed `.ckdb` per app as the schema source of truth, `xcrun cktool` export/validate/deploy against Development (management token from an env file, passed positionally since cktool rejects piped stdi.
