fix: handle tags without 'v' prefix in deploy workflow

The release tag '2.0.0' (no 'v') caused all deploy conditions
(startsWith 'refs/tags/v') to evaluate false, skipping Pack,
Upload Artifacts, and the entire deploy job.

- Change all conditions to startsWith(github.ref, 'refs/tags/')
- Replace hardcoded substring(11) with regex to strip 'refs/tags/v?' prefix,
  correctly handling both 'v2.0.0' and '2.0.0' tag formats
