fix(discord): push connected status when gateway is already connected at lifecycle start

When the Discord gateway completes its READY handshake before
`runDiscordGatewayLifecycle` registers its debug event listener, the
initial "WebSocket connection opened" event is missed. This leaves
`connected` as undefined in the channel runtime, causing the health
monitor to treat the channel as "stuck" and restart it every check
cycle.

Check `gateway.isConnected` immediately after registering the debug
listener and push the initial connected status if the gateway is
already connected.
