Query Builder Expression Aliases in Laravel 12.48

Laravel 12.48.0 adds query builder expression aliases for cleaner raw SQL, a BatchFinished event for batch lifecycle management, and JSON decoding flags for HTTP responses. The release includes a skipWhen method for CORS middleware, support for brackets and braces in translation strings, and isolated view compilation during parallel testing.
