Sophisticated Backpacks Legacy

1.1.1 (2026-10-23)

• Deposit to Nearby Chests button, beside sort: each item in the backpack goes into nearby containers (8 blocks by default) that already hold that item, as Quark's deposit button does. No-sort slots stay in the backpack.
• Merge Backpacks button: shows while another backpack is near (8 blocks by default), placed on the ground or worn by a player standing close. It pulls the items this backpack already holds out of those backpacks, to gather loot of a kind in one place. Their no-sort slots stay where they are, other players' worn backpacks count only while allowOpeningOtherPlayerBackpacks is on, and merged items skip this backpack's void and compacting upgrades.
• Both ranges are in the config (nearbyActions); 0 removes the button.
