Story Crater Bot e706f62a83 feat: rewrite portfolio cards for recruiter-scannable impact
- Reorder projects: Poimen Orchestration → Memory → Homelab → RBC → AWS
- Add Poimen (Ποιμήν) timeline card with Graph-RAG + Temporal pillars
- Rewrite all 6 timeline cards: bold frameworks, quantified impact, emoji sections
- Update Homelab card: production-grade framing, milestone-driven bullets
- Fix CI status links: update API allowlist for riotpiao-poimen org repos
- Fix commit SHA: Dockerfile NEXT_PUBLIC_COMMIT_SHA + CI --build-arg
- Connect Poimen Memory card as 'the memory layer behind Poimen'
