Changes:
- Added 6 new tasks for Sprint 3 Phase 2 (Advanced Query Parsing)
- Fixed duplicate task ID CogStack#19 → renamed new task to CogStack#25
- Updated Next available ID: 26 → 31
- Updated header stats: 6 pending, 24 completed

- Phase 1 complete, Phase 2 next (Advanced Query Parsing)
- Tasks follow TDD approach (tests first)
- Include auditor and tester agents for validation
- Enable autonomous loop to continue development

Spec Reference:
- .specify/tasks/sprint-3-full-text-search-tasks.md (Phase 2)
- .specify/plans/sprint-3-full-text-search-plan.md (30 hours Phase 2)

Next Steps:
