Add InteractNearest() and LootAllCorpses() as registered Lua C functions,
ported from the standalone interact DLL. Uses the existing Lua protection
bypass instead of NOP-padding trampolines.
- interact.zig: game API wrappers, object scanning, loot queue with
SceneEnd hook for per-frame processing
- Bindings.xml: keybinding definitions loaded via LoadUIBindingsFromFile
(called explicitly since our virtual addon bypasses LoadAddonRecursive)
- Lua addon: BINDING_HEADER_WEIRDUTILS, Interact() wrapper, /wu interact
