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'
