"""Core settings in config.json must never be reported as orphaned plugins.

Observed on a v3.4.0 device: the web UI showed "Plugin Config Warning -- In
config but not installed: auto_update. Reinstall via the Plugin Store, or
remove these entries from config.json." ``auto_update`` is the top-level core
section #581 added for weekly automatic updates. Reconciliation kept its own
private list of non-plugin keys, which #581 did not know to extend, so any
top-level dict it did not list was treated as a plugin id. Following the
warning's advice deletes a real core setting.

These tests pin the shared list in src/core_config_keys.py to the sources that
actually define top-level keys, so the next new core setting cannot regress it.
