Extract Phase 3-4 shipping content (quality check, code review, PR
creation, quality checklist, code review tiers) from ce:work and
ce:work-beta SKILL.md into on-demand references/shipping-workflow.md
files. This content rode in context for the entire Phase 2 execution
loop without being used until the very end.
Both skills get identical reference files. Contract tests updated with
dual-read pattern: positive assertions read from reference files,
negative assertions stay on SKILL.md to confirm extraction completeness.
