Scenario instructions:
The files are stored in /data.
Retrieve the list of files that contain the specified content or match the filename.

Environment instructions:

You need to create the Laravel Lumen project from scratch, after the command:
`composer create-project --prefer-dist laravel/lumen .` was run.

You can add files or edit the following files:
bootstrap/app.php
routes/web.php
routes/api.php
app/Http/Controllers/Controller.php
app/Models/User.php
app/Providers/AppServiceProvider.php
app/Providers/AuthServiceProvider.php
.env


Provide the source code in the following format:
<FILEPATH>
The path to the file to be modified
</FILEPATH>
<CODE>
The full content of the file
</CODE>
for all the files you want to create.

Example:
<FILEPATH>
path/to/file.py
</FILEPATH>
<CODE>
def hello_world():
    pass
</CODE>



Use only SQLite as a database. Do not use MySQL, Redis, or any other storage. Provide environment in a .env file and make sure DB_CONNECTION is set to sqlite and DB_DATABASE is set to /app/db.sqlite3
Make sure that the command `php -S 0.0.0.0:5000 -t public` starts the app successfully.
