Hi team,

I would like to open a PR to suggest using Prettier for unified formatting across the project. The PR will:

• Add Prettier config (e.g., print width, quotes, trailing commas) and ignore files
• Add a format script (npm run format)
• Apply formatting to the codebase in a separate commit

This would help standardize spacing, quoting (single/double), and other style rules across collaborators.

Let me know please your thoughts on this.

Thanks!
