feat(claude-config-maintainer): add settings.local.json audit feature v1.2.0

Add 3 new commands for auditing and optimizing Claude Code permission
configurations, leveraging the marketplace's multi-layer review architecture.

New commands:
- /config-audit-settings - 100-point scoring across redundancy, coverage,
  safety alignment, and profile fit
- /config-optimize-settings - apply optimizations with dry-run, named
  profiles (conservative, reviewed, autonomous), consolidation modes
- /config-permissions-map - Mermaid diagram of review layer coverage

New skill:
- settings-optimization.md - 7 sections covering file formats, syntax
  reference, consolidation rules, review-layer-aware recommendations,
  named profiles, scoring criteria, and hook detection

Updated agent maintainer.md with new "Audit Settings Files" responsibility.
