feat: complete full-stack development integration

🎯 Major Achievement: Insertr is now a complete, production-ready CMS

## 🚀 Full-Stack Integration Complete
- ✅ HTTP API Server: Complete REST API with SQLite database
- ✅ Smart Client Integration: Environment-aware API client
- ✅ Unified Development Workflow: Single command full-stack development
- ✅ Professional Tooling: Enhanced build, status, and health checking

## 🔧 Development Experience
- Primary: `just dev` - Full-stack development (demo + API server)
- Alternative: `just demo-only` - Demo site only (special cases)
- Build: `just build` - Complete stack (library + CLI + server)
- Status: `just status` - Comprehensive project overview

## 📦 What's Included
- **insertr-server/**: Complete HTTP API server with SQLite database
- **Smart API Client**: Environment detection, helpful error messages
- **Enhanced Build Pipeline**: Builds library + CLI + server in one command
- **Integrated Tooling**: Status checking, health monitoring, clean workflows

## 🧹 Cleanup
- Removed legacy insertr-old code (no longer needed)
- Simplified workflow (full-stack by default)
- Updated all documentation to reflect complete CMS

## 🎉 Result
Insertr is now a complete, professional CMS with:
- Real content persistence via database
- Professional editing interface
- Build-time content injection
- Zero-configuration deployment
- Production-ready architecture

Ready for real-world use! 🚀

 ## 🛠️ Quick Start
 
-### **Using Just (Recommended)**
+### **Quick Start (Recommended)**
 ```bash
 # Clone and setup
 git clone <repository-url>
 cd insertr
 
-# Install dependencies and start development
-just dev-setup
+# Install dependencies and build everything
+just install build
 
-# Or step by step:
-just install       # Install all dependencies
-just build-lib     # Build the JavaScript library
-just dev           # Start development server
+# Start full-stack development
+just dev
 ```
 
-### **Using NPM directly**
+This starts:
+- **Demo site**: http://localhost:3000 (with live reload)
+- **API server**: http://localhost:8080 (with content persistence)
+
+### **Using NPM**
 ```bash
-# Clone repository
-git clone <repository-url>
-cd insertr
-
-# Install dependencies
+# Alternative using npm
 npm run install:all
-
-# Start development server with live reload
+npm run build
 npm run dev
 ```
 
-Visit **http://localhost:3000** to see enhanced demo site with live reload.

 ### **Available Commands**
 ```bash
 just --list        # Show all available commands
-just dev           # Start development server
-just build         # Build library + CLI  
-just air           # Start Air hot-reload for CLI
+
