Move openspec/changes/{contracts-ssot,orchestrator} → archived/ (both shipped,
v2.7.13 and v2.7.17). Mark the roadmap's "Write/edit robustness" and "Claude
provider SDK" milestones as shipped (fuzzy-match.ts + checkpoints.ts; the
claude-sdk backend is live via CLAUDE_SDK_BACKEND in .env.host) and add a
v2.7.12–v2.7.17 shipped summary. Flag DEFERRED-WORK.md as superseded.
