Repo tidy: logs consolidated, 15/16 scripts tracked, docs synced (#615/#611/#603)

Run outputs moved to logs/ (incl. sda partition-table backup). New from
the 15:57-16:03 parallel session: 16-grow-root-online.sh (RAN: / = 431G
online, swap removed by design — GROW-ROOT-RUNBOOK superseded) and
15-docker-to-data2.sh (staged, not run). README/NEXT/RUNBOOK/REBUILD
reflect current reality. Moot rdp-testprep timer removed from the VM.
