Pull request overview

Adds first-class .env support so the template works out-of-the-box in non-Docker local/dev environments (and defaults safely in production), addressing issues around missing/invalid APP_ENV.

Changes:

• Introduce src/bootstrap.php to centralize autoloading + environment initialization and load .env via vlucas/phpdotenv.
• Switch console (yii) and web (public/index.php) entrypoints to use the new bootstrap.
• Document .env usage, add .env.example, ignore .env, and add the new dependency.
