Slimmer application skeleton: `app/Http/Kernel.php`, `app/Console/Kernel.php`, `app/Exceptions/Handler.php` consolidated into `bootstrap/app.php`.

New projects get the new skeleton. Existing apps can stay on the classic skeleton — both are supported. See the upgrade guide to migrate incrementally.
