PyPI storage limit blocks policyengine-us releases

PE-US release publication is currently blocked by PyPI project storage limits. The post-merge publish job for `1.691.10` built the wheel/sdist successfully, then failed on upload with:

```
400 Project size too large. Limit for project policyengine-us total size is 10 GB.
```

Example failing run: https://github.com/PolicyEngine/policyengine-us/actions/runs/25880049459

This matters for downstream repos such as `policyengine-us-data`: the latest PyPI version remains `1.691.3`, while `main` is at `1.691.10` and includes fixes needed for SNAP/TANF/vectorized calculations. Until this is resolved, downstream lockfiles need to use a GitHub commit source or cannot consume the fixed package from PyPI.

Likely resolution: request a PyPI project-size limit increase for `policyengine-us`, then rerun the publish workflow for the current `main` version.
