Fix workflow trigger: add tags to top-level trigger

The workflow was not triggering on tag pushes because the top-level
'on' section only included branch pushes. Tag pushes were ignored
entirely, so the release job conditions were never evaluated.

This adds 'tags: ["*"]' to allow the workflow to trigger on any tag push.
