### Added

 * Introduced the `vip_files_acl_is_valid_path_for_site` filter to extend the `is_valid_path_for_site`
   function. This new filter allows overriding the VIP File System’s validation 
   process for multisite setups, which uses the `/wp-content/mu-plugins/files/acl/
   endpoint-check-file-acl.php` endpoint to check permissions for paths under `/
   wp-content/uploads`. It enables custom use cases, such as accessing directories
   outside the default site asset paths (but within the uploads folder) while adhering
   to other ACL rules. This extends the functionality introduced in PR #1975.
    **
   Warning:** Improper use of this filter could expose private data. Developers 
   using it must ensure that the logic they implement enforces proper access control
   to prevent data leaks between subsites.
