simulate(tui): silence stderr loggers, refresh summary before the report

- SDK/protocol logs written to stderr during the alt-screen session all
  spilled into the terminal when the TUI exited; discard them like the
  console and perf commands do (the agent log and run report carry the
  diagnostics).
- The run summary, which carries the chat transcripts, could land after
  the TUI's last poll; refetch once at exit so the report file includes
  the transcripts, and say explicitly when they aren't available yet.
