docs: enhance CLI help system for AI agents and users

Improved guardian --help with comprehensive, actionable information:
- Add DETECTS section with quick fix instructions for all 8 violation types
- Add SEVERITY LEVELS explanation (CRITICAL → LOW)
- Add step-by-step WORKFLOW guide
- Add 7 practical EXAMPLES covering common use cases
- Add HOW TO FIX COMMON ISSUES reference section

Technical improvements:
- Extract all help text strings to CLI_HELP_TEXT constants
- Fix 17 hardcoded string violations
- Maintain Single Source of Truth principle
- Zero violations in Guardian's own codebase

The help system now provides complete context for autonomous AI agents
and clear guidance for human developers.
