test: Add demo files for Enhanced Parser V2 testing

Added files:
- demo_v2.py: Interactive demonstration of Enhanced Parser V2
  * Shows real-world code analysis with LJPW framework
  * Demonstrates bug detection (semantic disharmony)
  * 5 examples including harmonious and disharmonious code
  * Validates Parser V2 features: 184 verbs, compound patterns

- test_example.py: Simple test code for CLI demonstration
  * Contains harmonious functions (get_user_data, validate_email)
  * Contains disharmonious function (delete_user_account bug)
  * Used for manual testing of Harmonizer CLI

Test results:
- All 82 tests passing (59 pytest + 23 standalone)
- Enhanced Parser V2 working correctly
- Bug detection functioning (disharmony score 1.225 for semantic bugs)
- Demo successfully shows all LJPW dimensions in action
