Cookies lost when headers off

Medium Severity

In metadataToContext, cookie and set-cookie metadata are merged into the same map passed to FilterRequestHeaders. When HTTPHeaders.Request uses CollectionOff, that helper returns nil for the whole map, so filtered cookie metadata is dropped even while CollectCookies() remains enabled.
