// What a build calls itself: its version, or "development".
//
// The version - package.json's - only for a build of a release: CI building a
// pushed v<version> tag, a checkout sitting exactly on that tag, or the master
// branch. Anything else, the development branch above all, is "development":
// a build from in-between commits is not the release its package.json names,
// and showing that number in Settings > About said it was.
//
//   node scripts/version-label.mjs            -> "1.0.0" or "development"
//   node scripts/version-label.mjs --channel  -> "release" or "development"
//
// Imported by electron.vite.config.ts; run by the daemon build scripts, which
// hand the answer to nobilis (NOBILIS_CHANNEL), whose own checkout cannot
// tell - CI checks a submodule out as a bare commit, on no branch.
