S00-024: Record blocked task and remediation handoff

Changes: Preserve incomplete work and blocker metadata for S00-024. This checkpoint does not mark implementation accepted.
Validation: Session ended with status blocked.
Blocker: S00-024 cannot establish readiness for S00-020: official checksum retrieval fails with configured proxy DNS error and host Node/npm differ from accepted pins; no partial environment-access artifacts exist.

Task: S00-024
Agent: auto-ci-cd-988167c541cf
