Remove test/index.js and replace lodash with pure JavaScript

- Remove test/index.js (functionality covered by separate test files)
- Replace complex omit function with simpler removeLocationProperties
- Remove lodash and esbuild from devDependencies (unused)
- All 32 tests passing, functionality preserved
