Add TypeScript to the Project

[fabiovincenzi]

Goal

Set up TypeScript with an initial loose configuration while ensuring JavaScript files remain executable.

Tasks

• Install TypeScript dependencies (typescript, @types/node).
• Create a tsconfig.json file with loose settings.
• Ensure the project builds successfully.

Notes

• Start with a minimal tsconfig.json, then adjust settings incrementally.
• Ensure JavaScript files can still be executed without requiring immediate conversion to TypeScript.

Closing this - should be all done after #1174 is completed!
