v1.0.23 — Portal Cache + Leaf Decay Optimizer + Item Frame Optimizer

Performance modules:

• Portal Cache (portal-cache) — Caches Nether portal destination links to skip Minecraft's O(radius³) block-scan search on repeated uses. The first portal use populates the cache by capturing the resolved destination; all subsequent uses of portals in the same chunk resolve instantly without a block scan. Configurable TTL, per-world disable.
• Leaf Decay Optimizer (leaf-decay-optimizer) — Rate-limits leaf decay events per chunk per tick. Large trees or tree-feller plugins schedule hundreds of simultaneous leaf decays, each triggering 6 block physics updates — cascading into multi-tick freezes. Cancelled events auto-reschedule so leaves still fully disappear, just spread across more ticks. Lag-aware mode can halt all decay during severe TPS drops.
• Item Frame Optimizer (item-frame-optimizer) — Freezes item frames (including map-art frames) that are beyond any player's visibility radius so they stop ticking. Frames unfreeze instantly when a player comes within range. Uses Paper 1.17+ entity freeze API; silently skips on Spigot/older. Optional per-world hard cap removes excess frames far from all players.
