Initial commit: Shelfless – alternative Audiobookshelf frontend

React + Vite + TypeScript SPA covering the full ABS feature set (library
browsing, item detail, metadata/cover editing, podcasts, player with session
sync, admin: users/libraries/scanner/server settings). Dev uses a dynamic
CORS proxy; production is served by server/index.mjs (static + reverse proxy
to ABS_URL). Includes systemd unit and installer under deploy/.
