ItemSaver

First release.

• Armor Guard: a helmet, chestplate, leggings or boots down to their last 10 durability points are moved into the inventory automatically. A full inventory is reported rather than failing quietly, and the guard holds off while another container is open.
• Tool Warnings: any damageable item in the hotbar or offhand under 5% durability gets a pulsing red slot with the remaining percentage above it, plus a chime and an action-bar line when it crosses.
• Pieces that cannot be helped are reported rather than skipped silently: an elytra is warned about instead of removed, Curse of Binding is reported once, and nothing is unequipped while gliding.
• Two rebindable toggle keys under Options → Controls → ItemSaver; thresholds and cosmetic toggles in config/itemsaver.json.
