Arthercord Visual Compatibility 2.2.0

The compatibility add-on contains original Java code and a declarative repair policy.
It contains no copied third-party Pokemon mesh, texture or animation artwork.
At client startup it reads artwork already installed with Cobblemon, Mega Showdown,
Complete Cobblemon Collection and Synchro Machine, then generates a local resource
cache. Original asset copyright and source licenses remain with their authors.
Do not redistribute the generated cache as a replacement for the original mods.

- Mega Showdown 1.3.1+1.8.2+1.21.1-release

- Cobblemon Synchro Machine 1.8.1 (locator metadata only)

The build tools, Java source, transformation policy and validation scripts are
provided beside this add-on. Third-party binaries remain external dependencies.
