Add multi-agent workflow examples

Adds two step-by-step workflow examples showing how to coordinate
multiple agents for real projects:

- Startup MVP: 7 agents across a 4-week build cycle
- Landing Page Sprint: 4 agents shipping a page in one day

Each example includes exact prompts to copy, handoff patterns, and
tips for passing context between agents. Checks off the
"Multi-agent workflow examples" item from the roadmap.

+# Multi-Agent Workflow: Landing Page Sprint
+
+> Ship a conversion-optimized landing page in one day using 4 agents.
+
+## The Scenario
+
+You need a landing page for a new product launch. It needs to look great, convert visitors, and be live by end of day.
+
+## Agent Team
+
+| Agent | Role in this workflow |
+|-------|---------------------|
+| Content Creator | Write the copy |
+| UI Designer | Design the layout and component specs |
+| Frontend Developer | Build it |
+| Growth Hacker | Optimize for conversion |
+
+## The Workflow
+
+### Morning: Copy + Design (parallel)
+
+**Step 1a — Activate Content Creator**
+
+```
+Activate Content Creator.
+
+Write landing page copy for "FlowSync" — an API integration platform
+that connects any two SaaS tools in under 5 minutes.
+
+Target audience: developers and technical PMs at mid-size companies.
+Tone: confident, concise, slightly playful.
+
+Sections needed:
+1. Hero (headline + subheadline + CTA)
+2. Problem statement (3 pain points)
+3. How it works (3 steps)
+4. Social proof (placeholder testimonial format)
+5. Pricing (3 tiers: Free, Pro, Enterprise)
+6. Final CTA
+
+Keep it scannable. No fluff.
+```
+
+**Step 1b — Activate UI Designer (in parallel)**
+
+```
+Activate UI Designer.
+
+Design specs for a SaaS landing page. Product: FlowSync (API integration platform).
+Style: clean, modern, dark mode option. Think Linear or Vercel aesthetic.
+
+Deliver:
+1. Layout wireframe (section order + spacing)
+2. Color palette (primary, secondary, accent, background)
+3. Typography (font pairing, heading sizes, body size)
+4. Component specs: hero section, feature cards, pricing table, CTA buttons
+5. Responsive breakpoints (mobile, tablet, desktop)
+```
+
+### Midday: Build
+
+**Step 2 — Activate Frontend Developer**
+
+```
+Activate Frontend Developer.
+
+Build a landing page from these specs:
+
+Copy: [paste Content Creator output]
+Design: [paste UI Designer output]
+
+Stack: HTML, Tailwind CSS, minimal vanilla JS (no framework needed).
+Requirements:
+- Responsive (mobile-first)
+- Fast (no heavy assets, system fonts OK)
+- Accessible (proper headings, alt text, focus states)
+- Include a working email signup form (action URL: /api/subscribe)
+
+Deliver a single index.html file ready to deploy.
+```
+
+### Afternoon: Optimize
+
+**Step 3 — Activate Growth Hacker**
+
+```
+Activate Growth Hacker.
+
+Review this landing page for conversion optimization:
+
+[paste the HTML or describe the current page]
+
+Evaluate:
+1. Is the CTA above the fold?
+2. Is the value proposition clear in under 5 seconds?
+3. Any friction in the signup flow?
+4. What A/B tests would you run first?
+5. SEO basics: meta tags, OG tags, structured data
+
+Give me specific changes, not general advice.
+```
+
+## Timeline
+
+| Time | Activity | Agent |
+|------|----------|-------|
+| 9:00 | Copy + design kick off (parallel) | Content Creator + UI Designer |
+| 11:00 | Build starts | Frontend Developer |
+| 14:00 | First version ready | — |
+| 14:30 | Conversion review | Growth Hacker |
+| 15:30 | Apply feedback | Frontend Developer |
+| 16:30 | Ship | Deploy to Vercel/Netlify |
+
+## Key Patterns
+
+1. **Parallel kickoff**: Copy and design happen at the same time since they're independent
+2. **Merge point**: Frontend Developer needs both outputs before starting
+3. **Feedback loop**: Growth Hacker reviews, then Frontend Developer applies changes
+4. **Time-boxed**: Each step has a clear timebox to prevent scope creep
