shoney.arickathil 4ad24d6381 docs(db2-migrate): close out iteration 12
- crash-before-rename test: a COMPLETE valid migrated temp beside the
  untouched original is discarded and the boot re-migrates — the
  sharpest point on the crash timeline, deterministic, no fault
  injection needed
- story: all six tasks done with commit hashes, all eight criteria met
  with the test that proves each, plus the three deviations from the
  plan and why (transcode over replay, lazy head, poison forces
  transcode)
- CODE-LOGIC: migration section; also corrected limitation 3, which
  still claimed unbounded hot-row chains — iteration 11 closed that
- status board row 12; deploy guide's rollback section gets its real
  answer (rolling back across a migration is a migration backwards:
  expect the refusal, restore the .bak)
- test_wal 5966 pass, 0 fail
