Deprecated License Expression in `pyproject.toml`

[Grochocinski]

Describe the Bug

The pyproject.toml file contains an outdated license classifier (License :: OSI Approved :: MIT License) and raises the following warning when the package is built: By 2026-Feb-18, you need to update your project and remove deprecated calls or your builds will no longer be supported.

Steps To Reproduce

1. Run uv sync to resolve dependency versions and install dependencies
2. Run uv build to build the package (building manually via setuptools works too)

Expected Behavior

No warnings when building the package
