Animation event tables now come from CreateUnsecuredObjectPool and are
wiped on release, keeping garbage down under 1.12's stop-the-world GC.
Release the tables that were previously dropped for the GC (hidden
events, the power-gain early return), and make /msbt stats report the
number of tables in use as a leak check.
Add .pkgmeta (package-as MikScrollingBattleText, move-folders pulling both addon folders to top-level siblings) and a tag-triggered GitHub Actions workflow using BigWigsMods/packager that attaches the single zip to an auto-created GitHub release. Switch both TOCs' Version to the @project-version@ substitution token so the packager stamps the git tag version.
