Add core Ox modules as ES modules with tests

This commit adds ES module versions of fundamental Ox utilities:
- Array utilities (api, compact, unique, zip, etc.)
- String utilities (capitalize, clean, truncate, wordwrap, etc.)
- Math utilities (trig functions, geographic calculations, etc.)
- Object utilities (clone, serialize, keys/values, etc.)
- Function utilities (cache, debounce, throttle, memoize, etc.)
- Constants (math, time, colors, HTTP status codes)
- Polyfills for older browser compatibility

All modules include proper imports/exports and maintain the same API
as the original implementations. Added comprehensive test coverage with
31 tests passing.

Next steps: Convert remaining core modules, set up build pipeline,
and test backward compatibility with existing examples.
