    aiohttp 3.14.0 (pulled in to fix GHSA-jg22-mg44-37j8 and GHSA-hg6j-4rv6-33pg):
      * removed ``aiohttp.streams.AsyncStreamReaderMixin`` (folded into ``StreamReader``),
        which vcrpy's ``MockStream`` still subclasses -- vcr's patch machinery then raises
        ``AttributeError`` at collection time; and
      * added a required ``stream_writer`` keyword-only arg to ``ClientResponse.__init__``,
        which vcrpy's ``MockClientResponse`` does not pass -- raising ``TypeError`` at
        cassette playback.

    Restore the mixin, then rebuild ``MockClientResponse``'s ``super().__init__`` call from
    the live ``ClientResponse`` signature (defaulting every required keyword-only arg to
    ``None``, mirroring vcrpy's original call) so it also survives future aiohttp additions.
