Sol's Item Rarity v1.5

This update focuses on inventory performance and smoother compatibility with Sol's Relic System.

What's new

• Added new visual performance options for rarity effects.
• Added an option to disable animated/chroma text while keeping static rarity colors.
• Added an option to disable animated border effects while keeping simpler colored borders.
• Added lighter border modes: Full, Simple, Static, and Off.

Performance

• Improved inventory GUI performance when many rarity borders are visible.
• Improved item border rendering performance in inventories, hotbar, and tooltips.
• Reduced FPS drops when hovering items with large tooltips, such as heavily enchanted books.
• Reduced repeated rarity checks while rendering tooltips, hotbar item names, colored item names, and slot borders.
• Reduced RAM/garbage-collection spikes caused by repeated rarity lookups during GUI rendering.
• Improved Minecraft 1.21.1 custom-data handling so rarity and SetID reads do less repeated NBT work.
• Cleanup now removes empty NBT/custom-data shells too, so fixed stackables can actually restack.

Config Behavior

• Visual handlers now bail out earlier when ItemRarity or its visual options are disabled.
• Disabling rarity visuals should feel lighter and more immediate in large inventories.
