 * BRIEF: Extract element name, type, type prefix, and ZIP name from manifest
 *
 * Usage:
 *   php manifest_element.php --path .
 *   php manifest_element.php --path . --version 09.01.00 --stability dev --github-output
 *
 * Detects platform (joomla, dolibarr, generic) and resolves:
 *   ext_element   — canonical element name (e.g. mokojgdpc)
 *   ext_type      — extension type (plugin, module, component, package, etc.)
 *   ext_folder    — group/folder for plugins (e.g. system)
 *   ext_name      — human-readable name (e.g. "Moko JGDPC")
 *   type_prefix   — Joomla type prefix (plg_system_, com_, mod_, etc.)
 *   zip_name      — computed ZIP filename
