feat: Create hello world script

[pokryfka]

Task

Create hello world script

Plan

1. Create a new file named hello_world.py in the scripts/ directory.
2. Add a shebang line #!/usr/bin/env python to allow the script to be executed directly.
3. Define a main function that prints the string "Hello, World!".
4. Use a standard if __name__ == "__main__": block to call the main function, which is a best practice for Python scripts.

Summary by CodeRabbit

• Chores
  • Added a development utility script to the scripts directory.

📝 Walkthrough

Walkthrough

A new Python script has been added at scripts/hello_world.py that prints "Hello, World!" to the console. The script includes a standard shebang, defines a main function, and uses the conventional guard to execute the main function when run directly.

Poem

🐰 A script so simple, a greeting so true,
Hello World arrives, fresh and brand new,
With shebang and function, it's ready to run,
The smallest of features, but oh what great fun! 🌍

scripts/hello_world.py (1)

1-1: Prefer a Python 3 shebang (and verify runtime is 3.12+).

#!/usr/bin/env python is interpreter-ambiguous. Use python3 to better align with the Python 3.12+ requirement.

Suggested patch

-#!/usr/bin/env python
+#!/usr/bin/env python3

As per coding guidelines, "Use Python 3.12+ with async throughout the agent loop".

Python 3 shebang (change "#!/usr/bin/env python" to "#!/usr/bin/env python3"),
and add a runtime version guard at program startup (e.g., in your main() or the
if __name__ == '__main__' block) that checks sys.version_info >= (3,12) and
exits with a clear error if not. Also ensure the program entry uses asyncio
(e.g., call asyncio.run(main())) so the agent loop runs async throughout;
reference the module-level shebang line, the main() function (or the __main__
block), and any async agent loop code when making these edits.

- Around line 1-2: The module scripts/hello_world.py is missing the required
future annotations import; add the statement from __future__ import annotations
at the very top of the file (immediately after the shebang) so the module
(hello_world.py) complies with the repo coding guidelines.
