contains(s, needle: (u8|[]u8)) -> contains(s: []u8, needles:
(u8|[]u8)...) bool per ref/hare/bytes/contains.ha:6.
Body: for-loop over needles.len; inner match (needles[i]) with u8/
[]u8 arms each forwarding to index(s, ...) with early return true
on the i32-match arm. 0-arg returns false per Hare spec. Mirrors
sister #9 strings.contains body shape modulo element type.
Sister of #9 (7c5463c). Element shape (u8|[]u8) — slice payload +
scalar u8 — structurally distinct from (str|rune). Was flagged as
potential new-latent surface; verified clean by 967_bytes_run +
cross-module 750_mklabel_modscoped[bytes_strings_contains] +
995_self_rebuild byte-id. No cgen wedge fired — #15 frame growth +
#12 sum-tag forward + #16 fnparamslookupmod close it on the slice-
payload variant too.
contains_cases adds 5 variadic rows (signalled 1700+i): 0-arg false,
1-arg slice hit, 1-arg u8 hit, 3-arg mixed middle-hit, 3-arg all-miss.
Module-header non-variadic divergence note removed.
make test 126/126; ww2==ww3==ww4 byte-id holds via 995_self_rebuild.
