// Only the release workflow stamps a real version. It sets PLG_RELEASE, and its
// GITHUB_RUN_NUMBER is the same number as the release tag it publishes
// (v1.0.<run-number>), so the shipped APK knows its own version and the in-app
// updater can compare against the latest published release.
//
// Everything else — a local build, or the dev CI pipeline — stays at 1.0.0-dev.
// GITHUB_RUN_NUMBER alone is NOT enough to key off: it counts per workflow, so
// the dev pipeline has its own independent sequence. A debug APK installed from
// a CI artifact would otherwise carry that counter as its versionCode, could
// outrank a genuine release, and would leave the updater reporting "you're on
// the latest version" indefinitely.
