// Release pipeline of the storebound desktop app. Builds, signs, checks and lays out one version for

//   bun tools/desktop-release.ts mac [--out <dir>] [--target-dir <dir>] [--identity "<Developer ID Application: ...>"]
//        [--no-notarize] [--notes "..."] [--allow-dirty]
//     Universal (Apple silicon + Intel) app, updater bundle (.app.tar.gz) and DMG. With a "Developer ID Application"
//     identity in the keychain: hardened runtime, notarization (notarytool, App Store Connect API key) and stapling.
//     Without one: an ad-hoc signed build named `-unsigned`, and what the owner has to do. Must run in the owner's
//     local GUI session: codesign over SSH fails (the keychain is locked there), so SSH sessions are refused.
//     The built window is booted headless first (tools/desktop-boot-check.ts). Then, on the exact artifacts: codesign / Gatekeeper expectations, the self-test (sidecar handshake, both CPU
//     types) from the mounted DMG and from the unpacked updater bundle, the privacy scan, minisign signatures with
//     the updater key (~/.storebound-keys/updater.key), SHA256SUMS, latest.json and evidence.json.
//   bun tools/desktop-release.ts add --out <dir> <files...> [--code-signed]
//     Adds Windows / Linux installers built by the Forgejo workflow (.forgejo/workflows/desktop.yml) to the version
//     folder: privacy scan, minisign signature here (the key never goes to a runner), latest.json, SHA256SUMS.
//   bun tools/desktop-release.ts publish --out <dir> --host <user@host> [--channel stable|beta] [--yes]
//     Checks the folder again, uploads it to the server's incoming folder (rsync) and runs the root-owned publish
//     script there (tmp -> mv, latest.json last). Without --yes it only prints the plan (dry run).
//   bun tools/desktop-release.ts verify --out <dir>
//     The checks of publish without uploading.
//   bun tools/desktop-release.ts exec -- <command...>
//     Runs a build command (tauri build on a runner) with the path-free environment described at pathFreeEnv.
//
// Version: package.json "desktopVersion" (bun tools/desktop-version.ts). Docs: docs/desktop-release.md.
