aioresponses 0.7.8 (latest) does not pass the stream_writer keyword
argument that aiohttp 3.14 made required on ClientResponse, so every
aioresponses-mocked HTTP test fails to construct a response. core
declares aiohttp>=3.9 with no upper bound, so CI floated to 3.14.0 and
the backend job would break on the next run. Pin <3.14 in the test
install in both build.yml and release.yml until aioresponses ships an
aiohttp-3.14-compatible release.
