Simple AutoPickup

Features

• New Experience Gamerule: Added a new gamerule, autoPickupXp, to allow independent control over the automatic pickup of experience orbs. It is enabled by default. This gives users full control over how items and experience are collected.
• Mending Compatibility: The XP that is automatically picked up now goes to one of the items to mended before giving the leftover xp to the xp bar. This is done though a damage first mend later approach using an experience cache system.

Technical & API Changes

• Unified Experience Cache: The internal logic for handling experience from both block breaks and mob kills has been refactored into a single, universal caching system. This simplifies the codebase, improves performance, and makes the mod more resilient and future-proof.
