Module click 

Validated container-click input.

SContainerClick carries three raw fields (slot_num: i16, button: i8, ClickType) whose meanings depend on each other: -999 means “outside the window”, the swap button is a hotbar index or 40 for the offhand, and a drag click bit-packs its phase and kind into button. Click::parse decodes and validates all of that once at the packet boundary. Every slot index inside a Click is in range for the menu it was parsed against, so the click handlers in Menu start at their actual logic instead of re-validating raw integers.
