fix: pair-agent server dies 15s after CLI exits 

The server monitors BROWSE_PARENT_PID and self-terminates when the
parent exits. For pair-agent, the connect subprocess is the parent,
so the server dies 15s after connect finishes. Disable parent-PID
monitoring for pair-agent sessions so the server outlives the CLI.
