refactor: make hwlocality optional and streamline release workflow

Extracts release creation into a dedicated `create-release` job that outputs a shared `release_id`, allowing downstream build jobs to upload binaries directly and ensuring atomic initialization. Introduces a `numa` feature flag for `obikindex` to make `hwlocality` optional, providing graceful fallbacks like a synthetic UMA node when disabled. Also bumps `obikmer` to 1.1.16.
