fix(cli): add module= attribute extraction to element detection

Joomla modules declare their element via the module="mod_foo" attribute
on the entry <filename>, not via an <element> tag. Both manifest_element.php
and release_package.php were missing this extraction, causing incorrect
element names and ZIP filenames for module-type extensions.

Added module="..." regex check in the element detection chain for both
files, matching what updates_xml_build.php already had.
