## 🔧 Technical Implementation
### Server Infrastructure (CommyServer)
All examples use the same pattern:
```rust
// 1. Create server with config
let mut server = CommyServer::new(ServerConfig::default());
// 2. Prepare (download binary, generate certs)
server.prepare().await?;
// 3. Start (spawn process, wait for ready)
server.start().await?;
// 4. Use server URL
let client = Client::new(server.url());
// 5. Cleanup (automatic via Drop)
```
### Key Features
- ✅ Automatic binary download (checks target/ directories)
- ✅ Self-signed TLS certificate generation
- ✅ TCP-based ready detection (100ms polling, 5s timeout)
- ✅ Process lifecycle management
- ✅ Graceful shutdown handling
- ✅ Resource cleanup on drop
