/**
 * Core knows no plugin by name.
 *
 * Fails when anything under src/ spells a plugin id: a bare literal
 * ("docker"), a plugin route ("/plugin-api/docker/..."), or an action, slot
 * or permission id that starts with one ("docker.open"). What core needs from
 * a plugin comes through the registries instead. Regex literals are read too,
 * so /^\/plugin-api\/docker/ counts the same as "/plugin-api/docker".
 *
 * Plugins live in their own repos, so the ids are the official ones below
 * plus anything in docker/bundled-plugins.json. electron/ and vite.config.ts
 * are read as well.
 *
 * src/backend/tests, src/ui/tests and src/ui/locales are exempt, and so is
 * src/backend/upgrade/: the one-time
 * 2.8 to 2.9 data moves have to name the plugin each piece of data moves to,
 * the same way LEGACY_TABLE_OWNERS in the SDK names the plugin that adopts
 * each legacy table.
 *
 * One plugin id is also an SSH term: "totp" is the one-time-code prompt kind
 * in keyboard-interactive auth, which the connect pipeline in
 * src/backend/hosts/connect/ classifies. It is not the login plugin.
