Subject: tools/mm/page_owner_sort: show available sort keys in usage text
Date: Wed, 19 Aug 2026 10:16:11 +0800

The --sort option accepts abbreviated or complete key names, but the usage
text never listed them.  Users had to read the source or the documentation
to discover valid keys.

List all available keys (full form and abbreviation) with a brief
description and examples directly in the --sort help section.
