N_ALLOC is a vestigial nkind enum entry. Defined in cstage
cmd/wcc/ww.h:243 (comment: "lhs=expr, rhs=size-or-null") and
mirrored in lib/ww/ast.ww:47, but no parser produces it — the
alloc-call syntax routes via N_CALL with callee=alloc (check.ww
:1479). Cstage cexpr has no case N_ALLOC; wwstage's listing it
in the post-dispatch kind set at check.ww:482 was speculative.
Remove the disjunct. Enum entry stays — sync with ww.h is the
gate, not stamp-coverage. Broader dead-kind audit tracked as
task #18.
A.6.2 step 3 of 8 (γ order).
`make test-unit` green; full `make test` batched per option B.
