Adds concurrently to start both the Vite frontend and Hono backend simultaneously in one terminal via the `bun run dev` command. Also updates documentation in README.md and CLAUDE.md to reflect the new development workflow.
Add README with Docker setup instructions for self-hosting. Update
docker-compose.yml to use the pre-built registry image instead of
local build, and add a healthcheck against /api/health.
