KOS_OP_CALL_VAR_NAMES

• Style: EXTRA. Schema: VAR (name cpool idx), CONST (kw names tuple cpool idx), COUNT (npos), NOARG.

• Stack: [..., pos_0, ..., pos_{N-1}, kwd_val_0, ..., kwd_val_{M-1}] → [..., result]. Callable from namespace by name; kw names tuple from constant pool. Same call semantics as CALL_NAMES.

• Compiler form: Not emitted by the compiler; available for manual bytecode construction.
