refactor: Update to millpond.dev domain and remove marketing content

🔧 Professional domain + open-source focus

**Changes:**

1. **Domain Update (4 references):**
   - millpond-storefront.pages.dev → millpond.dev
   - README.md: Badge + live demo link
   - CHANGELOG.md: Reference implementation link
   - examples/millpond/README.md: Live site link

**Why:** Professional custom domain (millpond.dev) is:
- Cleaner and more memorable
- Production-ready branding
- No Cloudflare Pages subdomain clutter

2. **Removed PUBLISH_CHECKLIST.md:**
   - Marketing/launch strategy content
   - Not relevant for open-source academic pattern
   - Contained internal planning (HN, Product Hunt, outreach)
   - Better kept in private project management

**What Remains:**
✅ Core academic documentation
✅ Technical implementation guides
✅ Research foundations
✅ Community contribution guidelines
✅ Reference implementation (MillPond)

**Open-Source Focus:**
- Pattern documentation (not marketing)
- Technical guides (not launch plans)
- Academic credibility (not growth hacking)
- Community value (not promotional content)

**Note:** millpond.dev custom domain verification in progress
Expected resolution: Within 24 hours (Cloudflare DNS propagation)
