<!-- CURSOR_SUMMARY -->

> [!NOTE]
> **Low Risk**
> Messenger registration and type exports only; no change to polling
behavior itself.
> 
> **Overview**
> Registers the existing **`stopAllPolling`** polling API on
**`SubscriptionController`** so other packages can invoke it via the
messenger as **`SubscriptionController:stopAllPolling`**.
> 
> Adds **`SubscriptionControllerStopAllPollingAction`** to the
method-action types union, includes **`stopAllPolling`** in
**`MESSENGER_EXPOSED_METHODS`**, exports the action type from the
package entrypoint, and documents the change in the changelog.
