get npm build to somehow work

- Enhanced build system to generate ESM, UMD, and minified formats
- Fixed test extraction script to properly parse OxJS inline tests
- Added comprehensive test infrastructure with Vitest
- Successfully extracted 22 test files from inline documentation
- Verified builds work in browser and Node.js environments
- Maintained full backward compatibility with Ox.load() pattern
- Updated .gitignore to exclude build artifacts (dev/, min/, dist/, test/extracted/)

Generated with AI assistance
