Valen Python SDK 0.2.0

Stable 0.2.0 GitHub distribution of the Valen HTTP and modular ONNX SDK. No request/response schema break from the 0.2.0 development API. See the bilingual README, CHANGELOG.md and RELEASING.md for installation, optional dependencies and backend-specific compatibility.

Packaged Python: 28 contract tests. Packaged JavaScript: 12 contract tests and TypeScript declarations checked. Both final distributions passed Linux CPU cached 0.8B ONNX FP32 text inference; Python stable/development baseline and JavaScript probabilities matched exactly. Prior media/CUDA/WebGPU evidence is reused separately, not generalized to untested platforms. Assets, licenses, metadata and credentials were checked before publication.

Python 0.2.0 is now published on PyPI: https://pypi.org/project/valen-sdk/0.2.0/ . Trusted Publishing succeeded in https://github.com/Valen-Team/valen-sdk-python/actions/runs/40286898341 . The PyPI wheel and sdist inventory was verified; the downloaded wheel passed SHA256 verification, matched this GitHub release Python source, installed offline with no dependency downloads, and passed 28 contract tests. PyPI and GitHub archive hashes are recorded separately because build metadata can differ. Install HTTP clients with python -m pip install valen-sdk==0.2.0, or local CPU inference with python -m pip install "valen-sdk[onnx]==0.2.0". JavaScript npm publication is separate and remains pending npm authorization.
