fix(cli): replace process.exit(1) with process.exitCode = 1

process.exit() forcefully kills the process, preventing libuv from
cleanly closing HTTP connections (undici). On Windows this triggers
an assertion failure: UV_HANDLE_CLOSING.

Using process.exitCode = 1 lets Node.js exit gracefully after the
event loop drains, eliminating the assertion error while still
returning exit code 1.
