Subject: [PATCH] Add showcase release workflow and gitignore build artifacts

- Remove 541MB of committed Electron build artifacts from git
- Add .gitignore patterns for release/, *.apk, *.aab, *.ipa
- Add GitHub Actions workflow for building showcase releases
  (manual dispatch with version input, builds Linux desktop +
  Android APK, creates GitHub Release with attached artifacts)
