feat(wiki): port upstream knowledge quality improvements

Selectively port source coverage and redirect lint, ignore-aware provenance, staging and trust checks from upstream 055d720. Preserve local archive metadata and adapt source-date and defuddle skill guidance.

Keep the existing skills directory, file index and MCP interfaces. Record per-module upstream baselines and exclusions without migrating vault data or changing services.

Validation: 625 tests passed; git diff --check passed.
