Fix GitHub Release permissions and version propagation

- Add explicit permissions for contents:write and packages:write at workflow level
- Set LIB_VERSION as global environment variable from inputs or default (0.1.0)
- Simplify version configuration to use global env variable consistently
- Fix release tag generation to use the global LIB_VERSION
- Remove dependency on passing version between jobs via GITHUB_ENV

This ensures the release creation has proper permissions and the version
is correctly propagated throughout the workflow.
