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.

+### Settings Scoring System

+The settings audit uses a 100-point scoring system across four categories:
+
+| Category | Points | What It Measures |
+|----------|--------|------------------|
+| Redundancy | 25 | No duplicates, no subset patterns, efficient rules |
+| Coverage | 25 | Common tools allowed, MCP servers covered |
+| Safety Alignment | 25 | Deny rules for secrets/destructive ops, review layers verified |
+| Profile Fit | 25 | Alignment with recommended profile for review layer count |

+### Permission Profiles

+| Profile | Use Case |
+|---------|----------|
+| `conservative` | New users, minimal auto-allow, prompts for most writes |
+| `reviewed` | Projects with 2+ review layers (code-sentinel, doc-guardian, PR review) |
+| `autonomous` | Trusted CI/sandboxed environments only |

 ### Usage Guidelines
 
 - Run `/config-analyze` periodically to assess CLAUDE.md quality
+- Run `/config-audit-settings` to check permission efficiency
 - Target a score of **70+/100** for effective Claude Code operation
 - Address HIGH priority issues first when optimizing
 - Use `/config-init` when setting up new projects to start with best practices
+- Use `/config-permissions-map` to visualize review layer coverage
 - Re-analyze after making changes to verify improvements
