/**
 * One-time migration for CLIs upgrading from the local-file default project
 * (`selected-project.json`) to the backend-persisted per-user setting.
 *
 * When the legacy file is present and the account has no *stored* default
 * server-side (checked with `includeAutoPick: false`, so a transient
 * sole-project auto-pick does not count — see the inline note below), its
 * project is pushed up as the new default. A stored default set on another
 * machine / the web takes precedence. The file is then removed so this runs at
 * most once per machine.
 *
 * Entirely best-effort: any failure (unreadable file, network, older backend)
 * is swallowed and the file left in place to retry — a missed migration just
 * means the user re-runs `auth set-project`, which is the pre-migration status
 * quo. A corrupt file is discarded.
