rtx-fsi: report Newton rescue counts in the coupling-failure panic

FSI3 run 3 died on a coupling stall 0.2 s after the rescue carried it past run 2's Newton death, and the panic path printed nothing about how many rescues had engaged. Observability only — the panic message now carries rescue_counts. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01Lnyrw33Lu6rUhW42E9KHwq
