fix: Align subscription status mapping with tRPC state machine

Browse Source 
tRPC subscriptions use connecting/pending/error/idle — not success.
The old code mapped pending→isConnecting and waited for success (which
never fires), causing AgentOutputViewer to permanently show "Connecting...".

Now: connecting→isConnecting, pending→isConnected, idle→disconnected.
