/**
* Force a reconnect — call from native lifecycle hooks (e.g. Capacitor
* appStateChange) and browser visibility events.
*
* iOS kills WebSocket connections during background without updating
* readyState, so we NEVER trust the old socket after a foreground
* transition. Always tear down and create a fresh connection. Any
* sends that arrive during the reconnect window queue in pendingSends
* and flush after the welcome handshake completes.
