When Codex CLI is installed via `npm`, we use a `.js` wrapper script to launch the Rust binary. - Previously, we were not listening for signals to ensure that killing the Node.js process would also kill the underlying Rust process. - We also did not have a proper `exit` handler in place on the child process to ensure we exited from the Node.js process. This PR fixes these things and hopefully addresses https://github.com/openai/codex/issues/1570. This also adds logic so that Windows falls back to the TypeScript CLI again, which should address https://github.com/openai/codex/issues/1573.
