Remove macOS remnants from CI/PR template; illustrate README

- ci.yml: drop the macOS build job (Xcode/xcodegen/build.sh); keep the
  Linux test job and move the secret-hygiene scan into it
- PR template: replace ./build.sh checklist item with the Linux test
  suite; fix "macOS preview scope" -> "Linux preview scope"
- README: add a control-panel + tray hero image and a Screenshots
  gallery (settings tabs + hands-free wakeword)
- Track Screenshots/wakeword.png

The BlitztextMac/ source tree, root build.sh, and stale docs/screenshots
were removed from the entire git history in a separate history rewrite.
