refactor: implement runtime plugins with declarative configuration

This major refactoring replaces hardcoded runtime configuration with a plugin-based system:

- Created a new plugin system that loads runtime configurations from YAML files
- Added support for dynamic runtime detection based on OS and architecture
- Implemented proper binary path handling with platform-specific adjustments
- Improved runtime installation with better error handling and logging
- Added support for both tar.gz and zip packages for cross-platform compatibility
- Added comprehensive tests to verify the new functionality
- Removed the old node-utils.go and consolidated logic in runtimes-installer.go

This change makes adding new runtimes much simpler and more maintainable.
