v0.3.1

[0.3.1] - 2026-10-07

Fixed

• Read __version__ from the installed package metadata. The 0.3.0 wheel still reported 0.2.0.
• Point the license attribution and the README citation at the 0.3.0 tree.

Changed

• Cap supported Python at 3.11 and 3.12 (requires-python is >=3.11,<3.13), the interpreters the release workflow runs.
• Publish the GitHub Release from this section, after PyPI accepts the files.
• Document every run_from_config key and the four output status codes.
• Lock the status comment, the run_grid docstring, the release changelog pattern, and the README Python lines to the kernel and the CI matrix.
