Hi @imanchalsingh 👋

I'd love to fix this bug as part of SSoC '26!

• Fix: Remove the duplicate export default from validateEnv.js — only one export default is allowed per module in JavaScript/ES modules.
• Verify: Confirm the server starts without SyntaxError: Only one default export allowed per module errors.
• Check: Audit related files for similar duplicate export issues.

Could you please assign this to me (@arcgod-design)? Thank you!
