docs(frank-archon): the ttm reset outage, and the 4 x 200,000 fp8 shape

Runbook gains the 2026-10-13 section (symptom signature, the runtime-knob law,
the shape arithmetic, the boot ledger that confirms it: 843,276 tokens =
4 x 200,000, 12 all-reduce rows, 5.87 GiB of KV lent to the slab). AGENTS.md
gains the fleet-row update, the KV dtype law at four slots, the sysfs-raise
lesson under Key Lessons, and the pinned-RAM paragraph now points at
scripts/ttm-preflight.sh as the repair. LLM index entry + topology node match.
