Morphica

This update fixes many player-disguise option issues, especially around setupsidedown, setanim, and the setskin flow. setanim was cleaned up, and clearing now only works with setanim none.

setname and setskin were adjusted to work independently, so the name should stay while the skin changes. Several client rendering and mixin crashes for Minecraft 26.1 were also fixed, including startup mixin failures.

Extra safety checks were added for ears/cape rendering with mods like minecraftcapes, and skin-resolving error messages were improved. There are still bugs.
