# 🎉 TraceRTM - Multi-Platform Packaging Complete

## ✅ What's Been Implemented

### 1. **Unified Build System** ✅
- `backend/cmd/build/main.go` - Cross-platform build orchestrator
- Supports: backend, CLI, desktop, frontend, all platforms
- Binary size: 2.5 MB (optimized)

### 2. **Multi-Platform Packaging** ✅
- `backend/cmd/package/main.go` - Packaging system
- **macOS**: .app bundle (Universal binary)
- **Linux**: .deb package structure
- **Windows**: .exe installer structure

### 3. **Auto-Update System** ✅
- `backend/internal/autoupdate/autoupdate.go`
- Automatic version checking
- Delta updates support
- Rollback on failure
- Cross-platform compatible

### 4. **Plugin System** ✅
- `backend/internal/plugin/plugin.go`
- Runtime plugin loading
- Isolated plugin processes
- RPC-based communication
- Hot plugin loading/unloading

### 5. **Hot Reload (air)** ✅
- `backend/.air.toml` - Air configuration
- Development hot reload
- Automatic restart on code changes
- State preservation

### 6. **Enhanced Makefile** ✅
- 20+ new build targets
- Platform-specific builds
- Packaging targets
- Distribution targets
