Instant Leaf Decay

# ⚡ Instant Leaf Decay - Hotfix Release This version completely addresses the critical crashes and performance freezes reported on singleplayer worlds and under heavy TNT explosion loads: * **🛡️ TNT Explosion Crash Fixed:** Traditional instant leaf decay mods recursively trace and break leaves instantly in a single tick. When tree farms are exploded with TNT, this triggers thousands of recursive block updates, causing severe CPU spikes or `StackOverflowError`. This version features a **queue-based scheduled decay manager** that limits decays to `250` leaf blocks per tick per world. This completely prevents stack overflow crashes and server watchdog freezes under high-load deforestation while decaying large forests rapidly and smoothly. * **🔌 Singleplayer Load Crash Fixed:** Resolved thread-safety and chunk-loading mixin conflicts in subclass methods. The mod now hooks safely into standard leaves tick executors, working perfectly for both server-side multiplayer and local singleplayer worlds. * **💨 Silent & Instant Decay:** Leaf blocks now disappear instantly and silently without spawning block break sound or particles, while still dropping saplings, sticks, and apples naturally. * **⚡ Lightweight & Server-Side:** Standard Fabric gameplay mod that is fully server-side compatible (clients do not need to install it to join).
