研究方向

The issue is about adding signal propagation to Tool::exec. Currently, signals sent to the Volta process are not forwarded to child processes. The implementation likely involves setting up signal handlers (e.g., using `signal hook` or `tokio::signal`) and forwarding them to the child process. Review existing code in `src/` to understand how `Tool::exec` works (likely using `std::process::Command`). Also, check the 12 comments in the issue for suggested approaches or pitfalls. Look at how other Rust CLI tools handle signal propagation for reference.
