PR #2171 by OdinKral: feat(scripts): add pattern/maintenance audit script

• Adds scripts/audit-patterns.sh, a dependency-free audit tool for the patterns library that detects thin patterns (under 15 lines), bloated patterns (over 50 KB), stale hardcoded model references, missing INPUT sections, i18n key gaps, and shell completion gaps. The script is read-only and exits with code 0 by default, or 1 when run with --strict for CI integration.
