* feat: add type hints for $app in artisan and public/index.php
Added PHPDoc type hints for the $app variable to improve static analysis
support in PHPStan and PHPStorm. This prevents tools from incorrectly
flagging the variable and enhances developer experience.
No functional changes; only improves code readability and IDE support.
* Update artisan
* Update index.php
