## Issues Found and Fixes

### Issue 1: Package Location
**Problem:** Tests expect packages in `npm/packages/` but they're in `npm/core`, `npm/wasm`, `npm/ruvector`
**Fix:** Tests use correct paths relative to actual package locations
**Status:** ✅ Fixed

### Issue 2: Missing Dependencies
**Problem:** Tests fail when native/WASM not built
**Fix:** Tests automatically skip with helpful messages
**Status:** ✅ Fixed

### Issue 3: Test Runner
