Mason Daugherty 34af59c1a6 fix(partners): cap aiohttp below 3.14 for vcrpy compat (#37898)
aiohttp **3.14.0** (released 2026-06-01) removed
`aiohttp.streams.AsyncStreamReaderMixin`. The current release of `vcrpy`
(8.1.1) still subclasses it in its aiohttp stub:

```python
class MockStream(asyncio.StreamReader, streams.AsyncStreamReaderMixin):
```

As a result, the VCR fixture fails to import during test setup, and the
scheduled integration tests for the `fireworks` and `xai` partners error
out at `test_stream_time`:

```
AttributeError: module 'aiohttp.streams' has no attribute 'AsyncStreamReaderMixin'
```

Only these two partners are affected because their SDKs use `aiohttp`,
so VCR loads its aiohttp stub; partners on `httpx` (e.g. `anthropic`,
`openai`) are unaffected.

This is an upstream incompatibility tracked at kevin1024/vcrpy#995, with
a fix in kevin1024/vcrpy#996 that has not yet been released.

Until a fixed `vcrpy` ships, this caps `aiohttp<3.14.0` via `[tool.uv]
constraint-dependencies` (the same mechanism already used for the
`pygments` CVE pin) in both packages. Using a constraint rather than
tightening the published `aiohttp>=3.9.1,<4.0.0` range means the change
only affects local/CI resolution — the package metadata users install
against is untouched. Both lockfiles re-resolve to `aiohttp` 3.13.5,
which still provides the removed attribute. A code comment points back
to the upstream fix so the pin can be removed once it lands.
