Add version management documentation and optional file support

- Add RELEASING.md with comprehensive release guide
- Update scripts/update_version.sh to gracefully handle missing conanfile.py
- Update .github/workflows/check-version.yml to skip optional conanfile.py
- Treat conanfile.py as optional file in release validation (in development on other branches)
