feat: publish all example components to GHCR and registry

- Add arxiv-rs and github-js to CI publish workflow matrix
- Add arxiv-rs, github-js, and memory-js to component-registry.json

These components were built but not published (arxiv-rs, github-js)
or published but not discoverable (memory-js).
