Go CLI commands moved to core/go-php. This repo now contains the Laravel modular monolith framework (previously php-framework). - Remove all Go files (now in core/go-php) - Add PHP framework: event-driven module loading, lifecycle events - Composer package: core/php - core/php-framework remains as-is for backward compat Co-Authored-By: Virgil <virgil@lethean.io>
