    Fix fatal error from FeedInterface::get_entry_count() breaking older WooCommerce Stripe Gateway (#65965)

    Remove get_entry_count() from product feed FeedInterface

    PR #64394 added get_entry_count() as a required method on FeedInterface,
    shipping in 10.9.0. Because the interface is implemented by third-party
    code — notably the WooCommerce Stripe Gateway's
    WC_Stripe_Agentic_Commerce_Csv_Feed — adding a required method is a
    backward-incompatible change. Stripe versions that predate their own
    get_entry_count() implementation (added in Stripe 10.7) fatal on load
    under 10.9.0:

      Class WC_Stripe_Agentic_Commerce_Csv_Feed contains 1 abstract method
      and must therefore be declared abstract or implement the remaining
      methods (...FeedInterface::get_entry_count)

    No core code calls get_entry_count() through the interface; the method is
    only used on the concrete JsonFileFeed (and by consumers on their own feed
    classes). Remove it from the interface to restore compatibility, keeping
    the implementation and its tests on JsonFileFeed intact.

+Remove get_entry_count() from the product feed FeedInterface to restore backward compatibility. Requiring the method broke third-party implementations (e.g. older WooCommerce Stripe Gateway versions) that implement the interface without it. The method remains available on JsonFileFeed.
