/**
 * Cascade-deactivate plugins that declare `Requires Plugins: desktop-mode`
 * when Desktop Mode itself is being deactivated.
 *
 * Without this, a third-party plugin like `wp-desktop-messages` keeps
 * its `init` hook armed after Desktop Mode is turned off — the next
 * admin page load fires `init`, the hook calls
 * `desktop_mode_register_window()`, and the request fatals because the
 * function lives in the plugin we just deactivated. The user lands on
 * a white screen instead of the classic admin we redirected them to.
 *
 * WordPress's plugin dependency feature (6.5+) blocks ACTIVATION of a
 * plugin whose declared `Requires Plugins` aren't all active, but it
 * does NOT auto-deactivate dependents when their requirement is
 * deactivated through any path — the user is expected to do that
 * themselves. The classic plugins.php list shows a warning; the REST
 * controller (`PUT /wp/v2/plugins/desktop-mode/desktop-mode`) we route
 * through has no such gate. So we cascade ourselves.
 *
 * Timing: `deactivate_plugins()` writes `active_plugins` to the DB
 * AFTER its hook loop finishes. If we call `deactivate_plugins()`
 * from inside our `register_deactivation_hook` callback, our nested
 * write-back is overwritten the moment the outer call runs its own
 * `update_option`. So we register the cascade to fire on
 * `shutdown` — by then the outer `deactivate_plugins` has finished
 * and our write-back sticks.
 *
 * Matching uses `WP_Plugin_Dependencies::get_dependents()` keyed on
 * our own directory slug (`dirname( plugin_basename( __FILE__ ) )`),
 * which is the same string the dependent's `Requires Plugins` header
 * resolves against. The filter below lets sites widen or narrow the
 * cascade — e.g. add a plugin that wraps `desktop_mode_*` calls in
 * `function_exists` guards and shouldn't be torn down with us.
 *
 * Silent deactivation (`$silent = true`) skips the dependent
 * plugins' own deactivation hooks. Those callbacks routinely call
 * `desktop_mode_*` helpers expecting Desktop Mode to be wired up;
 * firing them mid-cascade can trigger the same fatal we're trying
 * to prevent. Skipping them is the safer default.
 *
 * @since 0.18.4
