feat: Enhance verification system with AI protocol and dual-script approach

Makefile Integration:
- Add make verify-quick target for critical-only checks
- Fix verify-guidelines target to call comprehensive script
- Clear separation of usage patterns

AI Behavior Protocol:
- Add comprehensive AI instructions to both scripts
- Enhanced error/warning functions with AI reminders
- Multi-layered safeguards prevent automatic fixing
- Protocol applies to ALL file modifications

verify-quick.sh Enhancements:
- Basic documentation structure validation
- API content placement detection in README.md
- Maintains fast performance for development

Documentation:
- Comprehensive scripts/README.md with usage guidelines
- Bruno API tests validation explained
- Troubleshooting and compliance sections
- Clear AI protocol instructions and examples

This provides dual-script approach: fast critical checks during development,
comprehensive validation for pre-commit/CI, with AI safety across all operations.
