refactor: Reorganize repository structure for better maintainability

Major structural improvements:
- Created organized directory structure with logical separation
- bin/ directory for legacy scripts (poc.sh, prod.sh)
- config/ directory for configuration templates
- tests/ directory for test framework
- docs/ directory for documentation (ADRs)

Enhanced build system:
- Comprehensive Makefile with 20+ commands for development workflow
- Full CI/CD pipeline support (test, lint, security-check)
- Vendor integration testing for git vendor inclusion scenarios
- Development environment setup and configuration management

Updated test framework:
- Smart path resolution for both organized and vendored structures
- Improved vendor compatibility testing
- Enhanced error handling and timeout protection

Documentation updates:
- Updated README with new directory structure
- Comprehensive command reference and usage examples
- Clear vendor integration guidelines
- Architecture Decision Record for Node.js version management

Files moved:
- poc.sh, prod.sh → bin/ (legacy scripts)
- bitwarden-config.conf.sample → config/
- test-secrets-manager.sh → tests/
- ADR-Node.md → docs/

All path references updated to maintain full functionality.
This reorganization improves maintainability while preserving
compatibility for git vendor inclusion scenarios.
