fix: add explicit release name and version consistency checks to release workflow

The GitHub release was showing v3.1.3 instead of v3.2.0 because:
1. No explicit `name` was set on the GitHub release action, relying on
   defaults that could be unreliable
2. The sed command for extracting release notes used unescaped dots in
   the version regex, which could match wrong versions
3. No fallback if release notes extraction produced an empty file

Changes:
- Add explicit `name` and `tag_name` to softprops/action-gh-release
- Add version consistency check (tag vs pyproject.toml vs package)
- Escape dots in sed regex for exact version matching
- Add fallback when release notes extraction produces empty output
