Fixing Lint Errors

• Check project setup and install dependencies
• Run linting command to identify errors
• Fix identified lint errors
• Commit the fixes to the PR branch

✅ Lint error fixed successfully!

Fixed Issue:

• Missing beforeEach import in src/__tests__/server.test.ts:1 - The beforeEach function was being used but not imported from @jest/globals

The fix adds beforeEach to the existing import statement from @jest/globals. This should resolve the linting error that was causing the CI failure.
