Update version to 0.1.3 and simplify version output

- Update Cargo.toml version to 0.1.3
- Custom version flag implementation to output version only
- Update GitHub Actions to handle simplified version output
- Update Gitea Actions (action.yml) for version handling
- Now `ailog -V` or `ailog --version` outputs just "0.1.3"
