v0.0.0-beta.2 - Fix startup crash (DatagenModLoaderMixin)

Fixes the MixinApplyError: Invalid descriptor that caused the game to close immediately on startup with 0.0.0-beta.1.

Fixed

  • Startup crash common_toolkit.mixins.json:DatagenModLoaderMixin — the @Inject targeted DatagenModLoader.begin with an outdated Forge-era descriptor (5 booleans + Runnable / DataGenerator / Consumer). NeoForge 21.1.249 changed the signature to (Set, Path, Collection, Collection, Set, 6x boolean, String, File). The mixin has been corrected to match the real NeoForge method; the mixin transformer no longer fails during game initialization.

Notes

Library only — install as a dependency of another mod. No content on its own. Carry over the whole 1.21.1 / NeoForge 21.1.249 feature set from beta.1.
