/**
 * Build the Tauri updater manifest (`latest.json`) from signed bundles.
 *
 * Tauri's CLI produces `<artifact>` + `<artifact>.sig` when
 * `bundle.createUpdaterArtifacts` is on and TAURI_SIGNING_PRIVATE_KEY is set;
 * it does NOT write latest.json (that is tauri-action's job). This repo uses a
 * plain `npx tauri build`, so we assemble the manifest ourselves for the
 * endpoint configured in src-tauri/tauri.conf.json.
 *
 * On Linux the updatable artifact is the AppImage; deb/rpm users update through
 * their package manager, so only the AppImage is listed.
 *
 * Usage:
 *   node scripts/make-latest-json.mjs <bundle-dir> <version> <tag> <owner/repo> [out]
 * e.g.
 *   node scripts/make-latest-json.mjs src-tauri/target/release/bundle 0.6.0 v0.6.0 7sh1d0w7x/linux-doctor
