Summary

• Upgrade astral-sh/setup-uv to 9.0.0 and pypa/gh-action-pypi-publish to 1.14.2 while retaining full SHA pins.
• Refresh all uv-resolved dependencies to their latest compatible stable releases.
• Require uv_build>=0.12.2,<0.13 and disallow pre-release dependency resolution.
• Apply the Ruff and ty compatibility changes required by the upgraded development tools.
• Sort the example credentials JSON so the repository hook passes.
• Supersede the partial automated updates in chore(deps-dev): bump the uv group across 1 directory with 3 updates #231 and chore(deps): bump the github-actions group across 1 directory with 2 updates #242.
• Validate with just test, just build, all prek hooks, and 710 tests on both Python 3.12 and 3.13.
