  // loadAll() can activate them in the same startup pass.

  // above is constructed without a runtime-capable loader
  // (pluginLifecycleManager(db, { workerManager }) — no `loader` option), so
  // the lifecycle.load() that ensureBundledPlugins performs per newly
  // installed bundle only records the `ready` status and does not spawn a
  // worker (see activateReadyPlugin in services/plugin-lifecycle.ts).
  //
  // Managed instances (`plugins.autoInstall` from PAPERCLIP_MANAGED_CONFIG)
  // drive the key list from the control plane; self-hosted instances keep
  // the pre-existing behavior of ensuring only the kubernetes bundle.
  //
  // Resolution is deliberately synchronous and NOT fail-safe: an
  // unknown key or a path escaping the bundled catalog root throws out of
  // createApp so a managed instance refuses to start (positive allowlist,
  // fail closed).
  // SAFETY: installation is fully fail-safe. Any failure
  // (missing bundle, install error, load error) is caught, logged, and
  // swallowed per plugin so the server ALWAYS finishes booting. A degraded
  // boot (a provider unavailable, some agents cannot run) is strictly
  // preferable to a crash loop.
  //
  // The chain is not awaited here (createApp stays fast), but the settled
  // promise is exposed via `app.locals.bundledPluginsStartup` so boot steps
  // that must not outrun plugin availability — managed sandbox environments
  // (`applyManagedEnvironments`) run before the heartbeat resumes queued
  // runs — can sequence on it. It never rejects.
