claude-harness v0.1.6

CI adapters (the portable-core reach payoff): a .pre-commit-hooks.yaml + a composite GitHub Action gate any vault repo on the deterministic reference-integrity + health checks. They run the vault-graph-aware checks claude-harness uniquely owns (broken wikilinks / .canvas / .base, orphans, health) and compose with markdownlint / lychee / check-jsonschema for the commoditized ones -- see docs/ci-adapters.md. Also: a synthetic examples/vault/ (demo + CI smoke fixture) and a check-release gate (version-sync + manifest sanity) in CI. Docs: https://wombat164.github.io/claude-harness/
