Both stages were eagerly evaluating RHS regardless of LHS (eager ANDQ/ORQ on the two results). Now: eval LHS into AX, CMPQ $0 + JE/JNE to a per-call-site label, eval RHS into AX, fall through. AX holds the LHS sentinel on the skipped path — typechecker already enforces bool operands. Surfaced by lib/getopt's nil-argv guard segfault. Six new rows in test/wcc/700_e2e.c, three of which segfault pre-fix. lib/getopt test comment relaxed; nested-if kept as regression marker.
