Initial commit: CRDC Arrests API demo app

React + Vite static site demonstrating the CRDC School Arrest Rate API.
Features 6 interactive charts comparing observed arrest data against Bayesian
model estimates across U.S. school districts, with Civilytics visual identity.

- State selector and district search with 'interesting' suggestions (top arrests)
- Animated histogram loading grid showing posterior draw progress
- Charts: time series, rate by group, district vs national, model comparison quadrants, density proxy, exceedance probability
- Static JSON fixture for national rates (no API changes needed)
- Dockerfile + docker-compose.yml for self-hosted deployment
- GitHub Actions workflow and _config.yml for Git Pages
