feat(cli): add command-line support and update dependency configuration

- Introduce CLI argument parsing with clap in main.rs, enabling host, port, API, and password options.
- Validate the critical 'host' field and print help when missing.
- Update Cargo.toml and Cargo.lock with new dependencies (e.g., clap, anstream, etc.) to support CLI functionality.
- Revise README.md to reflect the new cmdline client usage.
- Remove config.toml to streamline configuration via CLI.
