KOS_OP_ITEM_VAR_TAKE

• Style: VAR (the key’s name).

• Stack: [..., obj] → [..., value]. Get obj[key], delete it, and push the value with the object on the stack and the key resolved by name.

• Cache: none; a VAR row survives lowering only for a name with no fast slot.

• Compiler form: Folded by the compress pipeline from VAR key, ITEM_TAKE. May lower to ITEM_FAST_TAKE.

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