fix: prevent reconnection loop on concurrent connection close

Browse Source 
- Don't reconnect when server closes old connection with code 4000
- Code 4000 means new connection was established, not an error
- Prevents infinite reconnection loop between old/new connections

Refs: terminal switching between 4000 error and connected
