feat: add argument parsing and module resolution for assistant app

- Implemented argument parsing in args.ts to handle root, home, and help options.
- Added parseHomeArg and parseHelpArg functions for command line argument handling.
- Created ModuleResolver class in assistant-app-resolve.ts to resolve module paths, including scoped packages and relative paths.
- Introduced caching mechanism for package.json reads to improve performance.
- Added utility functions for checking file existence and clearing the cache.
