refactor: Modernize CI/CD workflows with composite actions

- Replace custom update-version-files.sh with reusable composite action
- Replace custom create-release-notes.sh with softprops/action-gh-release@v2
- Add fail-fast validation for release workflow
- Fix file-version output reference (hyphen instead of underscore)
- Add conditional installation instructions for releases
