fix(release): handle prerelease tag builds

[SDAChess]

Summary

Fix prerelease tag builds so tags such as v0.1.0-pre.1 run the existing Release Tag workflow and publish prerelease artifacts without creating a GitHub Release.

Related Issue

None. This is a localized fix for the prerelease release workflow.

Changes

• Allow Release Tag to trigger for v*.*.*-pre.* tags.
• Keep prerelease publication in the existing tagged-release workflow.
• Normalize Python prerelease versions to PEP 440-compatible versions such as 0.1.0rc1.
• Make Release Dev explicitly calculate a dev version, preventing concurrently created tags from changing its artifact versions.
• Add coverage confirming dev builds ignore exact prerelease tags.

Testing

• nix develop -c uv run pytest python/release_tooling_test.py -q
  • 6 tests passed.
• nix run nixpkgs#actionlint -- .github/workflows/release-dev.yml .github/workflows/release-tag.yml
  • No workflow errors; only existing ShellCheck style/informational findings.
• git diff --check

Checklist

• The change is scoped to prerelease versioning and release workflow behavior.
• Focused tests pass.
• GitHub Actions workflows were validated with actionlint.
• The commit includes a DCO sign-off.
• Pre-commit was not run, as requested.
