Subject: [PATCH] fix: pass generic type T through to FetchOptions in $Fetch
 interface (#559)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The $Fetch interface accepts <T, R> generics but only passes R to
FetchOptions<R>, leaving T defaulting to any. This means FetchContext
and FetchResponse in hooks always have any type.

Fixed by passing T through: FetchOptions<R> → FetchOptions<R, T>
