Read commands from stdin, one per line. Execute each command as a subprocess.
For each command, print: "command: exit_code" where command is the original command text
and exit_code is the numeric exit code of the process.

After all commands, print a blank line followed by a summary line:
"passed: N, failed: M"
where N is the count of commands with exit code 0, and M is the count with non-zero exit codes.
