shoney.arickathil 1b6d633ed1 docs(db2-migrate): spec + story for schema migrations v1
- brainstorm settled: declarative and automatic at boot; v1 verbs are
  add and delete only; data/seed migrations deferred to v2
- added fields zero-fill by kind: the grammar has no field-default
  syntax and v1 refuses to grow compiler surface for it
- same-kind delete+add refuses as a disguised rename; retype and
  vanished classes refuse by name
- schema lives in the log itself: WO_WAL_SCHEMA head record, written by
  fresh-log open and compaction; name-keyed diff also closes the
  silent cid-renumbering hole
- story is iteration 12, board row added, db2-migrate prefix claimed
