Only what this pull adds. It is built on grain runs on a Rust server modelled on knotless, without hatk.

## Minimum app versions | ||
| ||
`web/static/app-version.json`, served at `https://grain.social/app-version.json`, | ||
is the oldest build of each app this server still serves. grain-serve hands the | ||
path to the pages, which answer it from `web/static`. The iOS and Android apps | ||
read it on launch and on returning to the foreground, and a build below its | ||
minimum shows a full-screen "Update Grain" that cannot be dismissed. Each app | ||
remembers the last minimum it read, so a blocked build stays blocked offline. | ||
| ||
The numbers are build numbers, not marketing versions: `ios.minimumBuild` is | ||
`CFBundleVersion` (`CURRENT_PROJECT_VERSION` in grain-ios's `project.yml`), | ||
`android.minimumVersionCode` is `versionCode`. `0` blocks nothing. Raise one | ||
only once the build it names is live in its store, or people are told to | ||
install an update they cannot get. | ||
