New Expressive Model Attributes in Laravel 13.2.0

Laravel 13.2.0 introduces several developer experience improvements. New symmetrical PHP attributes for Eloquent models (e.g., #[DateFormat], #[WithoutTimestamps]) replace multi-parameter attributes with single-purpose ones. Queue attributes #[Queue] and #[Connection] now accept backed enums directly without calling ->value. The withoutOverlapping() method gains a releaseOnSignal parameter to release overlap locks on process termination signals. UniqueConstraintViolationException now exposes column and index details per database driver. Other improvements include variadic #[Backoff] attribute support, magic factory methods accepting multiple arrays, schedule:list timezone fixes, and various bug fixes across queues, models, collections, HTTP streaming, and testing.
