feat: add Timeout middleware

Enforces a maximum request duration: the next handler runs in a goroutine with a
context deadline, and if it has not finished by the deadline the middleware responds
with 504 Gateway Timeout at the deadline — even for a handler that ignores the context.

Modeled on net/http.TimeoutHandler: the handler's output is buffered and written
through on success; if the deadline fires first the buffered output is discarded, a
504 is sent, and further handler writes return http.ErrHandlerTimeout. A canceled
parent context stops the handler without sending a 504. Panics propagate. Because the
response is buffered, http.Flusher and http.Hijacker are not supported (documented).
