v1.7.0

Warning

This build does not start. A packaging dependency (pywebview) was missing, so the
executable only opens a dialog reading No module named 'webview'. Download
1.7.3 instead — it is
verified to launch, and the release pipeline now runs the built application before publishing it.

What's Changed

• Add response security headers by @AurelioAvila in #4
