v2.1.0 — Content-Similarity Matching + Ender Chest Clipboard

Smarter Paste Matching

Paste now uses a 10-tier matching system that understands the difference between an item's identity and its state. A diamond sword with Sharpness V won't get swapped with a plain diamond sword anymore — paste prefers the closest match available.

Matching tiers (best to worst):

1. Exact match (same item, same components)
2. Identity match (same item, same enchantments/name — ignoring durability, container contents, repair cost)
3. Name + type match (same custom name and item type)
4. Content-similar match (shulker boxes/bundles with overlapping contents)
5. Type-only match (same item type, any components)

Within each tier, items not already in the correct position are preferred over items that would need to be moved.

Ender Chest Clipboard

Ender chests now have their own independent clipboard, separate from regular chests. Copy a layout in your ender chest and it won't overwrite your chest clipboard (or vice versa). Ender chest entries show with a teal label in the clipboard history browser.

Cross-pasting between ender chests and regular chests of the same size is still allowed.
