Pass app version and build id explicitly from Main.qml to AboutDialog
instead of relying on context properties inside the QML module scope.
Remove the confusing "Public beta" label.
Make Flatpak updates unmistakable after clients were stuck on the
May 1.0.3 commit. Expose bearwaveVersion/bearwaveBuildId to QML and
set the flatpak manifest version explicitly.
Restore the Flatpak manifest to the repo and target org.kde.Platform
6.10 instead of the EOL 6.6/23.08 stack reported in issue #5.
Add a maintainer build script and a CI job that verifies the manifest
builds against the current KDE SDK.
