fix: narrow fresnel return type to a two-element tuple#12466
Merged
Conversation
`fresnel` always returns a fixed two-element array `[ S(x), C(x) ]`, but
the declaration typed the return as the over-broad `Array<number>`.
Narrow it to `[ number, number ]`, matching the sibling `frexp` (which
returns `[ number, number ]`), and update the declaration test's
`$ExpectType` accordingly.
