feat: add quality_review task status and qualityReview initiative flag

Adds two new fields to the database and propagates them through the
repository layer:

- Task status enum gains 'quality_review' (between in_progress and
  completed), enabling a QA gate before tasks are marked complete.
- initiatives.quality_review (INTEGER DEFAULT 0) lets an initiative be
  flagged for quality-review workflow without a data migration (existing
  rows default to false).

Includes:
- Schema changes in schema.ts
- Migration 0037 (ALTER TABLE initiatives ADD quality_review)
- Snapshot chain repaired: deleted stale 0036 snapshot, fixed 0035
  prevId to create a linear chain (0032 → 0034 → 0035), then generated
  clean 0037 snapshot
- Repository adapter already uses SELECT * / spread-update pattern so
  no adapter code changes were needed
- Initiative and task repository tests extended with qualityReview /
  quality_review_status describe blocks (7 new tests)
- docs/database.md updated
