One jar for every loader and game version this mod supports, instead of one download per combination.
It bundles 21 builds: Fabric 1.15.2 through 26.2, Forge 1.16.5 through 1.20.1, and NeoForge 1.21.1 through 26.2. At startup a small bootstrap asks the loader which game version it booted and loads the matching build.
Why a bundle rather than one shared set of classes: the same code has to reference different Minecraft names depending on where it runs. Fabric ships intermediary names, NeoForge ships the official ones, older Forge ships SRG. Those cannot live in the same class file, so each build is kept separate inside the jar and stays invisible to the loaders' annotation scanners until it is needed.
Marked beta on purpose. The version selection and the class loading are covered by tests, but no build inside this jar has been started on a live server yet. The individual per-version downloads are unchanged and still the safe choice.
