Update Webpack config like scratch-storage

- Move build outputs into `dist/`
- Make build output file names more consistent
- Update `playground/index.html` for new output file name
- Explicitly specify target => Node output is much smaller
- Minor fixes / cleanup in `.gitignore` and `src/index*.js`
