Grimwake Reborn compatibility release

Includes the user-supplied Grimwake Datapack 1.0.57 Beta and Grimwake Resources 1.0.39 Beta under resourcepacks/legacy. Gameplay data and artwork are preserved unchanged; the combined pack.mcmeta labels this bundled edition. Original namespaces and creator metadata inside content remain intact.

The new menu and race integration are by Prince. Origins and Origins++ remain separate third-party mods with their original licenses and creator credits; their code/art is not included in this JAR. Imported origins retain the supplied mod or datapack as their provider.

Prototype Grimwake ability development is deferred at the user's request. The full preserved powers require Origins 1.10.2 for Minecraft 1.20.1 and any dependencies required by a specific external origin. The bundled resources are loaded automatically when the Origins bridge is available.
