Fine-Tuned Weaponry

### Improvements * MultiLoader project consolidated under `1.20.1/` with root README and `.gitignore` * Fabric player variables persist across sessions via world `SavedData` (parity with Forge capabilities) * Moon's Lunar Bloomfang passive throttled to every 20 ticks; no longer sets grass every tick * Gem trigger procedures refactored to use `GemNbtKeys`, `LivingEntity` queries, and level-scoped RNG * Consolidated weapon cooldown tooltips into `GiveWeaponTooltipProcedure` * Jauml config paths and item tags normalized from `finetunned` to `fine_tuned_weaponry` * Pinned `fabric-loom` to 1.9.2; removed stale MultiLoader template SPI files * VS Code launch configs use `${workspaceFolder}` paths ### Bug Fixes * Fixed Fabric player GUI page data lost on disconnect * Fixed redundant `createConfigFile` double-call in config procedures * Fixed `RandomSource.create()` usage in combat and crafting procedures
