Simple Data Objects Laravel Package

Migrate a PHP/Laravel codebase from spatie/laravel-data to std-out/simple-data-objects — finds every Data class, rewrites the class/attribute/cast/validation surface and the call sites to the SDO equivalent, flags what has no equivalent for human review, and verifies with the test suite. Also covers replacing hand-written XML-to-DTO import loops with lazyXml(). Use when the user asks to migrate, port, or replace spatie/laravel-data with simple-data-objects (or "SDO").
