// The release tag is the single source of truth for a stable build. Android
// refuses to install a package whose versionCode is not above the installed
// one and reports only "App not installed", so a hand-passed build number is
// a silent trap: pass a smaller one by accident and the release is dead on
// arrival. A semantic tag therefore DERIVES the number instead, which makes
// "1.1.14 is newer than 1.1.13" true by construction.
//
// Layout: X*1000 + Y*100 + Z, so 1.1.14 -> 1114 and 1.2.0 -> 1200. Dev builds
// tag themselves differently (forgejo-build-N-M) and keep the CI run number;
// they install under their own application id and never meet a stable build.
