ci: split GitHub Actions into separate CI and Release workflows

- Create dedicated ci.yml for push/PR testing to main branch
- Keep release.yml focused on version tag releases
- Remove unnecessary conditional checks from release workflow
- Cleaner separation of concerns for different trigger events

CI workflow triggers:
- Push to main branch: run tests only
- PR to main branch: run tests only

Release workflow triggers:
- Push version tags: run tests + publish + create release
