`jj | head` exits with non-zero code since `head` breaks the pipe. Also, removed `--color=always` from that command as it will shortly become unnecessary. Previosly, this caused the script to stop since it's run with `set -o pipefail`. Also, the operation id recovery code stopped working. We can use `jj debug operation` for this purpose now.
