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.

Hop, skip, and a Python leap,
A hello world so bright and sweet,
Eight lines of code, so crisp and clean,
The simplest script you've ever seen! 🐰✨

🛠️ Refactor suggestion | 🟠 Major

Add missing from __future__ import annotations import.

The coding guidelines require this import in every Python module. Also consider using python3 in the shebang to ensure Python 3 is explicitly invoked on systems where python might default to Python 2.

♻️ Proposed fix

 #!/usr/bin/env python
+from __future__ import annotations
 
+
 def main():

As per coding guidelines: "Include from __future__ import annotations in every Python module".
