Adds a custom server.ts (http server + Next request handler + a noServer:true WebSocket server on /ws) so the app can push live data without polling. A CollectorScheduler runs one interval-based job per docker/database widget instance, backed by dockerode against /var/run/docker.sock, and reconciles jobs when config.yml changes. Config hot-reload is now fully wired: chokidar watches config.yml/.env, re-validates on change, and broadcasts config:update (or a non-destructive config:error, keeping the last-good config) to every connected browser. The client subscribes to per-widget topics over a single shared WebSocket with exponential-backoff reconnect and last-result caching for instant resubscribe. Verified end-to-end against real throwaway containers (nginx, redis): live CPU/mem/uptime/health streamed over the socket, interval changes picked up without a server restart, and a broken config.yml correctly falls back to the last-valid config instead of crashing the app.
