Key corrections based on testing with fresh room SCWX:
- connections count includes ALL ever-joined players, not just active ones
(slots persist for reconnection, count never decreases)
- here field also includes disconnected players (slot reservation model)
- client/connected and client/disconnected confirmed as NOT delivered to
player connections after extensive testing
- Jackbox has no concept of "leaving" — player disconnect is invisible
to the API
- Added reconnection URL format (secret + id query params)
- Added error code 2027 (REST/WebSocket state divergence)
- Added ws-lifecycle-test.js for systematic protocol testing
