Migrate Agent Contracts

One-shot utility skill that migrates every agent under `.claude/agents/` to carry a tier-2 contract_version=1.0 frontmatter block, as required by Constitution Principle XI. Idempotent — agents that already have a contract are skipped verbatim. This skill is scheduled for removal after Phase B closes; its value is historical reproducibility.
