📝 WalkthroughWalkthroughThe change adds a shared health manager for readiness, memory pressure, and shutdown state. The server passes it to the proxy and API server. The proxy uses it for connection rejection. The API health endpoint uses it for health status. ChangesHealth and connection admission

Reject a nil Health in NewServer.
NewServer copies Managers without validation. If Health is omitted, DebugHealth dereferences the nil interface when no manual override is active. The /debug/health request then panics and is handled by Gin recovery instead of returning health status.
