Migrate ESLint config to eslint.config.js (Flat Config)

[Jagoda11]

Hi 👋

While checking out the project, I noticed that the ESLint setup still uses the older .eslintrc.js format, and the related packages (like eslint, @typescript-eslint/*, etc.) are a bit outdated.

I’d like to help modernize this by:

• Migrating to the newer eslint.config.js format (Flat Config)
• Updating the related dev dependencies to their latest stable versions

Flat Config is now ESLint’s recommended standard and allows easier upgrades going forward. All existing linting rules and behavior would remain the same—this would just be a format change to support future updates cleanly.

Would you be open to a PR for this? : YES!

Thanks!
