Function render_and_exit

atomic-cli/src/agent_error.rs:723–737

Terminal handler for `main`. clap's own display kinds (`--help`, `--version`, and the `arg_required_else_help` variant) are passed through untouched, including clap's original exit code. Everything else is re-rendered and exits 2, which means the command did not run.
