/**
 * Compute an app's display slug.
 *
 * Mirrors the server-canonical priority in
 * schema-api-server/api/admin/features/apps/installer.js:213 — private_id
 * (with the leading underscore stripped) wins over public_id. The orders
 * agree for the typical case where `private_id === '_' + public_id`, but
 * diverge for theme-collision suffixes (`_my_theme_1`) and any app where
 * `public_id` was set independently of `private_id`. Following the server
 * keeps CLI labels in sync with what the admin UI shows for the same row.
 *
 * No id fallback: an app with neither slug returns `undefined`. Callers
 * that want a "show something" guarantee (e.g. the push-app picker) should
 * append `?? app.id` themselves; the slug map deliberately filters such
 * records out so downstream code can flag them as `<not resolved>`.
