ci: trigger PyPI smoke tests after publish workflow completes

[jacalata]

Summary

• Adds workflow_run trigger so smoke tests fire automatically whenever Publish to PyPi completes
• Keeps existing daily schedule and manual dispatch

Note: workflow_run fires regardless of publish success or failure — add an if: github.event.workflow_run.conclusion == 'success' on the job if you want to skip on failed publishes.
