Inventory_Presser_REST::exclude_deleted_posts( array $args, WP_REST_Request $request )

Strips post IDs that no longer exist from a REST API collection query so that WordPress core never attempts to prepare a response for a deleted vehicle. The previous approach of using rest_prepare_{post_type} was too late — WP core had already read properties off the null post object and generated PHP warnings before the filter ran.
