- new tables ideas + idea_logs with FKs (User/Product/Pbi cascade rules per plan)
- claude_jobs.task_id nullable; new idea_id FK + kind enum + index
+ check-constraint: exactly_one(task_id, idea_id)
- claude_questions.story_id nullable; new idea_id FK + index
+ check-constraint: exactly_one(story_id, idea_id)
- notify_question_change trigger: handles null story_id; idea_id added to payload
Verified against dev DB: tables created, both check-constraints active
(neither-set insert correctly rejected with errcode 23514),
trigger replaced.
