What are you adding or changing, and what does it do?

Adds WaterSheep to data/open-models.yaml, in alphabetical order between Von and webml-kit. It's an open-weight decision model that answers Noul, Choice, Score and multi-label questions with a probability for every option. It can serve a local /v1/systemone endpoint for TypeSafe's Python SDK, or run in the browser through ONNX. The entry has a Chinese description, the Hugging Face model and demo as extra links, and the banner from its own README as the image.

Affiliation: I'm the author and maintainer.

• I edited a file in data/ and ran uv run scripts/build.py (no hand edits to README.md or scenarios/).
• The link points to the original source, not another list or directory.
• The description says what it does, starts with a capital letter, and ends with a period.
• Any image is hotlinked from the project's own pages.

I ran the build with plain Python rather than uv. --validate passes and the entry renders in pages/open-models.md; I left the generated files out of the commit since your Action rebuilds them after the merge.
