* PLUGIN LOADER ? convention-based file discovery.
*
* Scans plugins/ for .php files. Each returns an array:
* 'id' => string (required, unique)
* 'routes' => ['endpoint' => callable($pdo,$d,$uid,$is_admin,$dc)]
* 'views' => ['view_name' => callable():void]
* 'nav' => ['view_name' => 'Label']
* 'admin_only' => bool (applies to nav visibility)
* 'schema_version' => int
* 'schema' => string[] (SQL statements)
* 'etag_routes' => string[] (GET endpoints that use ETag caching)
* 'write_routes' => string[] (POST endpoints that bust stat cache)
*
* Plugin handlers use the same P11 contract as core: (PDO,array,int,bool,DateContext) ? [int,array]
