which runs a plain TCP server for receiving websocket hub clients, with server config, CSRF and rate limit middleware. - internal/websocket: Hub pushing messages to WebSocket clients (ServeHTTP, example.com/ws upgrade with optional CSRF check) and plain TCP clients (ServeTCP, newline-delimited JSON envelopes); ping/pong keepalive, per-client message rate limit, slow consumer handling, graceful Shutdown, debug logging of messages sent and received - internal/websocket/tcpserver: standalone TCP server for a hub, with accept back-off, a per-IP connection limit (server.websocket.connection_limit) and graceful shutdown - internal/cli/wsserve: `wsserve` command running the TCP server, with --listen/--host/--port overrides - internal/middleware: keyed token bucket rate limiter, real client IP from trusted proxies - internal/httpx: RFC 9457 problem responses, request IDs in context - internal/config: server section (host, port, shutdown timeout, rate limiter idle TTL, websocket); util.ByteSize settings (e.g. "32KiB"); lists of sections as single keys; empty lists stored as nil; isExplicitlySet for printLoadedConfig; JobSearchConfigSource renamed to JSCSourcesSource; TestSections checks every section's methods - internal/util: ByteSize, parsed and formatted with go-humanize
