Add enhanced dev server

[rotexdegba]

Use Laravel as inspiration:

dev-server-router.php

<?php
$uri = urldecode(
    parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH) ?? ''
);

// This file allows us to emulate Apache's "mod_rewrite" functionality from the
// built-in PHP web server. This provides a convenient way to test a Laravel
// application without having installed a "real" web server software here.
if ($uri !== '/' && file_exists(__DIR__.'/public'.$uri)) {
    return false;
}

require_once __DIR__.'/public/index.php';

php -S 0.0.0.0:8888 -t ./public dev-server-router.php
