Subject: [PATCH] feat(ST-1109.5): auto-mark PBI as DONE when all its stories
 are DONE on sprint close
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends completeSprintAction's $transaction with PBI status cascade:
- Pre-transaction: identify PBIs touched by this close (via stories.pbi_id),
  fetch each with all its stories
- Skip PBIs already DONE; skip PBIs with 0 stories
- Mark PBI DONE only when every story (post-decision) is DONE — stories
  outside the sprint are evaluated against their current DB status
- Promote-only: never demotes a PBI that becomes "incomplete" again
