Carry response chunks through LibRequests and ResourceLoader as a ResponseData wrapper. A disk cache hit can retain its mapped storage, while ordinary streamed chunks still use borrowed bytes. Store completed memory cache entries as Core::ImmutableBytes. This lets mapped disk-cache responses stay file-backed while retained by the HTTP memory cache, instead of forcing another ByteBuffer copy.
