LoliPickaxe Fabric

Compatibility-only port to Minecraft 1.21.9. Migrates renamed entity-world, profile, scoreboard, client-state and item-component APIs while preserving the frozen gameplay contract: no recipe, unbreakable extreme mining/combat, the defined 27 special drops, 32-block expanded right-click execution with lightning, 1024-block six-degree swing fallback, execution lifecycle and holder protection, same-item immunity, alternating bundled sounds, and no movement-speed boost. Built and release-contract verified with Java 21, Fabric Loader 0.19.3 and Fabric API 0.134.1+1.21.9; GitHub Actions passed.
