Epiphany - Modular Skill Tree

New Features

• Reward List: The reward field now supports multiple rewards, allowing a single Insight / Epiphany to trigger several effects at once
• Item Icon (item_icon): Added an item_icon field that lets developers easily set Insight and Epiphany icons via item IDs

Improvements

• Improved the drag interaction for Large Insight Tree
• Refactored and cleaned up the codebase for better maintainability

This update is theoretically backward compatible with existing datapacks, but backing up before upgrading is still recommended.
