feat: automate release workflow and add optional NUMA support

Refactor the Gitea release workflow to introduce a dedicated `create-release` job that exposes a shared release ID, eliminating redundant inline creation. Update the Makefile to automatically generate annotated tags with AI-derived markdown release notes from recent commits. Add an optional `numa` feature to `obikindex` that gates `hwlocality` behind conditional compilation, providing a graceful UMA fallback when disabled. Bump `obikmer` to v1.1.17.
