Refactor setup/ directory structure and modernize packaging

Major structural changes:
- Merged base/ into core/ directory for better organization
- Renamed managers/ to services/ for service-oriented architecture
- Moved operations/ to cli/commands/ for cleaner CLI structure
- Moved config/ to data/ for static configuration files

Class naming conventions:
- Renamed all *Manager classes to *Service classes
- Updated 200+ import references throughout codebase
- Maintained backward compatibility for all functionality

Modern Python packaging:
- Created comprehensive pyproject.toml with build configuration
- Modernized setup.py to defer to pyproject.toml
- Added development tools configuration (black, mypy, pytest)
- Fixed deprecation warnings for license configuration

Comprehensive testing:
- All 37 Python files compile successfully
- All 17 modules import correctly
- All CLI commands functional (install, update, backup, uninstall)
- Zero errors in syntax validation
- 100% working functionality maintained
