v0.37.2

Changed

• Documentation brought in line with the TDD workflow and the test skills. docs/getting-started
  (en/ja) gains the characterization step on the legacy path, what gate stages 2 and 4 hold the
  scaffold to, and the delivery path described as test-driven (walking-skeleton Issue, the
  test: → feat: → refactor: series, Fakes and injected Clock, reproduce-first fixes);
  README's delivery paragraph says the same; docs/architect-input-requirements (en/ja) lists a
  runnable legacy system — or a test-only datasource substitution — as an input for
  characterization tests; docs/scalardb-development (en/ja) documents the scaffold's test tree;
  OMNIGENT's quality-gate section names the stage 2/4 tasks and the clean-build rule; the
  skill-reference rows for export-backlog, implement-backlog and review-issue describe the
  current behaviour.
