on4kst: replace the legacy connection handling with a session-scoped supervisor using bounded connect, login and synchronisation timeouts, heartbeat and stale-link detection, controlled reconnect backoff and session-safe reader/writer queues; validate outgoing protocol context and malformed inbound user frames, enforce one locator per TCP session, publish complete user lists atomically and ignore repeated UE markers, prevent failed initial connections from entering a busy loop, add a compact high-visibility LINK state indicator, and remove false unhandled-frame reports. Solves #71
