One product per machine: the CLI and the desktop app share one version, the store accounts and the app folder list

- one version: package.json's version is the desktop app's too (desktopVersion removed); tools/desktop-version.ts
  keeps the plugin manifests and the app's copies equal, desktop-release publish refuses another version, release
  order app first then npm publish; the unpublished desktop 0.1.0 candidate is noted in the docs and CHANGELOG
- storebound desktop installs (per user, no admin: macOS DMG -> /Applications or ~/Applications, Windows NSIS /S,
  Linux AppImage + .desktop with the storebound:// handler), updates an older app, notes a newer one (downgrade only
  with --force), asks once ([Y/n], --yes, exit 3 without a terminal), opens on the folder; --dry / --json / --download;
  the install steps are pure plans (cli/lib/desktop-install.ts); the version's own manifest dl/<version>/latest.json
- credentials: one store, the CLI's credential profiles in ~/.storebound/credentials; the desktop writes and reads
  them (profiles.rs, files 0600), moves old keychain accounts into profiles on first start, shows profiles the CLI
  made; precedence env > named profile > project file > default profile; config `account`, "account" in the
  project's credentials.json; storebound accounts list | import (dedup by key id / service account e-mail, key files
  copied 0600, project file keeps keystore and review contact, backup, --dry, never prints values) | use
- app folders: one list ~/.storebound/projects.json shared by the desktop (registry.rs), storebound desktop,
  apps folders | add | remove, ws init and ws without a workspace file
- desktop: notice when a folder pins another storebound version; storebound-desktop --version
- tests: version drift, desktop decisions and per-OS plans, credential precedence and import, registry (TS + Rust),
  keychain migration and profile round trip (Rust), boot check with old keychain state and the new shared state
