Can Blueprint generate migrations for existing tables

1. Define the existing database schema in a YAML-based "draft" file:

yaml
models:
  User:
    username: string:128
    email: string:255
    password: string:255
    first_name: string:45
    last_name: string:45
    timezone: string:45
    location_id: id:location
    deleted_at: timestamp
    remember_token: string:255

2. Run the `blueprint:build` Artisan command to generate the migrations:

php artisan blueprint:build draft.yml

This will generate a migration file that matches the defined schema, including the table structure, columns, indexes, and foreign key constraints.

The generated migration will look something like this:

php
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('username', 128)->nullable()->index();
            $table->string('email', 255)->index();
            $table->string('password', 255);
            $table->string('first_name', 45)->nullable()->index();
            $table->string('last_name', 45)->index();
            $table->string('timezone', 45)->default('America/New_York');
            $table->unsignedInteger('location_id');
            $table->softDeletes();
            $table->string('remember_token', 255)->nullable();
            $table->timestamps();

            $table->foreign('location_id')->references('id')->on('locations')->onUpdate('cascade')->onDelete('cascade');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
};

This allows you to easily generate migrations for your existing database schema and integrate it into your Laravel application, without having to manually create the migration files.
