scaffold laravel 12 backend

composer create-project laravel/laravel + artisan install:api.
sanctum removed (custom session-cookie auth per ai/backend-context).
personal_access_tokens migration + config/sanctum.php deleted.
default .gitignore excludes vendor/, .env, etc - composer install
recreates vendor at setup time.
