Subject: feat(cli): match Composer's --version output format

Replace clap's built-in --version with custom handler that outputs
Composer-compatible version info: Mozart version line, PHP version
with binary path, and diagnose hint. Add detect_php_version_and_binary()
to mozart-core platform module.
