/**
 * What uninstalling removes — and, by default, what it does not.
 *
 * This logic lived in uninstall.php at the plugin root. Freemius refuses to
 * accept a deployment that ships that file (their build server answers a flat
 * HTTP 400), because their SDK owns the uninstall lifecycle and runs the
 * `after_uninstall` hook instead. So the logic lives here as a class, and
 * freemius.php wires it to that hook. Same behaviour, different doorbell.
 *
 * Data is KEPT by default. Only an explicit opt-out — "keep_data_on_uninstall"
 * set to false under Settings → Data — removes anything: a customer must never
 * lose configuration by deactivating or reinstalling the plugin.
