KOS_OP_ITEM_CLEAR

• Style: NOARG.

• Stack: [..., obj, key] → [...]. Delete obj[key] with the object on the stack and the key on the stack.

• Compiler form: Emitted by compile/del-item; the compress pipeline folds the run of feeders (bare VAR and CONST loads) ahead of it into the rows that name them.

• Implementation: koskari/lib/opcode/ITEM_CLEAR.c
