Dev: Ubuntu Touch install & update platforms (manual vs automatic, like Snap)

Ubuntu Touch (UBports) has two independent planes: OpenStore distributes confined click app packages, while the OS is updated as a whole system image via delta OTAs (image-based, not apt/dpkg for apps). App updates are user-triggered in OpenStore; OS OTAs are prompted, not silent.

WeKan applicability

A click-packaged web wrapper (webapp-container) in OpenStore, updated manually via OpenStore — or just the browser web app against a WeKan server.
