Modules are organized by category:

user_scanner/
├── dev/        # Developer platforms (GitHub, GitLab, etc.)
├── social/     # Social platforms (Twitter/X, Reddit, Instagram, etc.)
├── creator/    # Creator platforms (Hashnode, Dev.to, Medium, etc.)
├── community/  # Community platforms (forums, niche sites)
├── gaming/     # Gaming sites (chess.com, and many more(upcoming))

Module guidelines:

Each module must define a validate_<site>() function that takes a username and returns:
- 1 → Available
- 0 → Taken
- 2 → Error / Could not check
Use httpx for requests, colorama for colored output.
Optional: modules can define a CLI parser if they support custom arguments.
