feat(command-abstraction): refactor CLI command architecture and introduce new documentation

- Implemented a Command Abstraction Layer to eliminate ~1300 lines of duplicated code across tool commands, enhancing maintainability and consistency.
- Established a unified structure for argument parsing, ROM loading, and output formatting across all commands.
- Added comprehensive documentation, including a Command Abstraction Guide with migration checklists and testing strategies.
- Introduced better testing capabilities for command components, making them AI-friendly and easier to validate.
- Removed legacy command classes and integrated new command handlers for improved functionality.

Benefits:
- Streamlined command handling and improved code quality.
- Enhanced developer experience with clear documentation and testing strategies.
- Maintained backward compatibility with no breaking changes to existing command interfaces.
