docs: add problem statement and update to 4-tier testing in README

- Added 'Why This Template?' section highlighting problems being solved
- Added 'Quick Wins' section for immediate value proposition
- Updated all references from 3-tier to 4-tier testing (includes API tests)
- Simplified and beautified Mermaid diagrams for better presentation
- Added 'Before vs After' comparison showing ROI
- Restructured table of contents to lead with value proposition

Perfect for presentation - starts with problems, shows clear solutions

 # MXCP Project Deployment Template
 
-> 🚀 **Standardized deployment infrastructure for MXCP projects with proven CI/CD patterns**
+> 🚀 **Stop wasting days on deployment setup. This battle-tested template gives any MXCP project production-ready CI/CD in 5 minutes, with enterprise-grade security and monitoring built-in.**
 
-This template enables consistent deployment of MXCP servers across RAW Labs and external teams, with support for AWS App Runner and Kubernetes/Flux deployments.
+## 🎯 Why This Template?
+
+### Problems We're Solving
+
+**Without this template, every MXCP project faces:**
+
+🔄 **Deployment Drift**
+- Each project reinvents CI/CD from scratch
+- No consistency between projects (UAE uses one approach, Vertec another)
+- Knowledge isn't transferable between teams
+
+⏰ **Time Waste**  
+- 1 full day to set up deployment per project
+- Debugging the same issues repeatedly
+- Manual, error-prone deployment processes
+
+🔐 **Security Risks**
+- Secrets accidentally baked into Docker images
+- API keys exposed in build logs
+- No standardized secret management
+
+🚨 **Production Incidents**
+- "Works on my machine" syndrome
+- Missing environment variables in production
+- No standardized health checks or monitoring
+
+### The Solution
+
+**One template, infinite projects:**
+- **5 minutes** to full CI/CD (vs 1 day)
+- **Zero secrets** in Docker images
+- **4-tiered testing** catches issues early (data → tools → API → LLM)
+- **Battle-tested** in production
+
+## 🏆 Quick Wins
+
+Using this template immediately gives you:
+- ✅ Automated deployment to AWS App Runner on every push
+- ✅ Secure secret management (no more hardcoded API keys)
+- ✅ 4-tiered testing (data → tools → API → LLM)
+- ✅ Health monitoring and audit logs
+- ✅ Rollback capability with git tags
+- ✅ External team collaboration support (Squirro)

 ## Architecture Overview
 
+### Before vs After
+
+**Before this template:**
+- 10 projects = 10 different deployment approaches
+- 10 person-days of deployment setup (1 day × 10 projects)
+- Constant debugging of deployment issues
+
+**After this template:**
+- 10 projects = 1 template × 10 = consistency
+- Less than 1 person-hour total setup time (minutes per project)
+- Deployment just works™
