feat: Add CLI for PyServe with configuration options

- Introduced a new CLI module (`cli.py`) to manage server configurations via command line arguments.
- Added script entry point in `pyproject.toml` for easy access to the CLI.
- Enhanced `Config` class to load configurations from a YAML file.
- Updated `__init__.py` to include `__version__` in the module exports.
- Added optional dependencies for development tools in `pyproject.toml`.
- Implemented logging improvements and error handling in various modules.
- Created tests for the CLI functionality to ensure proper behavior.
- Removed the old `run.py` implementation in favor of the new CLI approach.
