 * BRIEF: Build ZIP and tar.gz install packages for Joomla/Dolibarr/generic projects
 *
 * Usage:
 *   php package_build.php --path /repo --version 04.01.00
 *   php package_build.php --path /repo --version 04.01.00 --output-dir /tmp
 *   php package_build.php --path /repo --version 04.01.00 --github-output
 *
 * Options:
 *   --path          Repository root (default: .)
 *   --version       Version string (required)
 *   --output-dir    Directory for built packages (default: /tmp)
 *   --type-prefix   Override type prefix (e.g. plg_system_)
 *   --element       Override element name
 *   --github-output Export zip_name, tar_name, sha256_zip, sha256_tar to $GITHUB_OUTPUT
 *
 * NOTE: Uses PHP exec() with escapeshellarg() for tar — all arguments are escaped.
