docs(frank-archon): rollback re-key after 2026-10-17 disk purge

The Swift1.5 w4dn8 .rad, the GLM-4.7 GGUF, and every derived model cache
were purged from dankserver (trash-staged, emptied with approval; 763 GiB
free). Rollback of the iq4r swap is now an HF re-download of the
byte-exact frank8465 mirror (LFS sha256 09dd9306...). Corrects the w4dn8
runbook header (still said LIVE) and rebuilds both Rollback sections;
log.md carries the purge record.
