wcc/ww: size/align/offset return untyped_int, not i32 (catB-9)

Browse Source 
wwstage's size/align/offset builtins returned i32 while their node
stamp was already untyped_int -- and cstage returns ty_untyped_int
(check.c:1570/1602). The diverging return false-rejected the canonical
Hare idiom `let x: size = size(T)` in wwstage (`let: not assignable
(i32 -> size)`) where cstage accepts; sha256.ww:189 was the live
casualty, quarantined as M_WWREJECT (#59.13) in the byte-id gate.

Align wwstage up: return untyped_int at the three sites (check.ww
size/align/offset). The len / slice .len / .cap returns stay i32 --
those match cstage (check.c:1534) and are correct. cstage is unchanged.

Regenerates the w6c and wwdump combined.ww. Full 990-997 byte-id holds
(a size()-mixing comparison emits CMPQ byte-identically on both stages,
so the untyped-int widening does not perturb the asm). Table-driven 844
test: the `let x: size = size(T)` family now compiles on both stages.
