// The app folders of this machine: one list shared by the CLI and the desktop app, ~/.storebound/projects.json
// (STOREBOUND_REGISTRY names another file). `storebound desktop` in an app folder, `storebound apps add`, `ws init` and
// the desktop's App folders screen add to it; `storebound apps folders` and the desktop show it; `storebound ws ...`
// without a storebound.workspace.json works over it. The desktop keeps its per-folder extras (mapped accounts, saved
// reads) in its own state by the same id. Only paths and names: no keys, nothing from inside the folders.
//   { "version": 1, "projects": [{ "id": "<16 hex>", "path": "/abs/folder", "name": "Star Dash", "added": "<iso>" }],

//                     "bundleId": "com.example.demo", "added": "<iso>" }] }
// storeApps: apps that are live on a store but have no project on this machine (`storebound apps add --store apple
// --app-id <id> --account <profile>`). The desktop shows them read-only (status, reviews, analytics) under that
// profile's account, noted "no local project"; they carry no path. Absent when there are none (older readers ignore it).
// Written atomically (temp file, rename); a missing or unreadable file reads as empty (an unreadable one is kept).
