Driver-Based Architecture in Spatie's Laravel PDF v2

Spatie's laravel-pdf v2 introduces a driver-based architecture that lets developers choose between multiple PDF generation backends: Browsershot (Chromium via Puppeteer), Cloudflare Browser Rendering API, DomPdf (pure PHP), and Gotenberg (Docker-based). The release adds queued PDF generation with callbacks, PDF metadata support (title, author, keywords, etc.), runtime driver switching, and custom driver support. Breaking changes include requiring explicit Composer installation of browsershot, config file restructuring, and dropping Laravel 10 support.
