chore(deps): add @jest/globals to fix build errors

[amotarao]

Summary

This PR adds @jest/globals as a devDependency to resolve TypeScript compilation errors during the build process.

Problem

When running npm run build, the TypeScript compiler fails with the following error:

error TS2688: Cannot find type definition file for '@jest/globals'.
  The file is in the program because:
    Entry point of type library '@jest/globals' specified in compilerOptions

This occurs because tsconfig.json specifies "types": ["@jest/globals"] in compilerOptions, but the package was not included in devDependencies.

Changes

• Added @jest/globals@^29.7.0 to devDependencies (version aligned with jest@^29.7.0)

Verification

• ✅ npm run build completes successfully
• ✅ All tests pass with npm test (294 tests passed)

Notes

This is a minimal change that only adds the missing dependency without modifying any code or configuration.
