Refactor build script for custom ISO creation and update hardware configuration

- Replaced OS-specific build method with a custom ISO builder in the build-for-hardware.sh script.
- Updated output file naming to reflect the correct Alpine version in the build process.
- Adjusted build dates in hardware configuration files for HP ProDesk, merged, and Start9 Pure profiles to the latest timestamp.

+# Building Complete Archipelago Node OS
+
+## Status: In Progress
+
+Currently building the Rust backend for Alpine Linux. Once complete, we'll have a fully functional Archipelago Bitcoin Node OS.
+
+## What's Been Completed
+
+### ✅ ISO Build System
+- Custom ISO builder using pre-built Alpine Linux
+- Hardware-specific builds (HP ProDesk, Start9, Dell OptiPlex, Generic)
+- Fast builds (~2 seconds)
+- No cross-compilation issues on ARM Mac
+
+### ✅ Frontend (Vue.js)
+- Production build complete
+- Location: `image-recipe/build/frontend/`
+- Size: ~14MB compressed
+- Includes: Dashboard, Apps, Marketplace, Container management, Settings
+
+### ⏳ Backend (Rust)
+- Currently compiling in Alpine Docker container
+- Native musl build for Alpine Linux
+- Will output single binary: `archipelago`
+- Includes: Container orchestration, RPC API, WebSocket support
+
+### ✅ Integration Scripts
+- `build-backend.sh` - Builds Rust backend in Docker
+- `build-frontend.sh` - Builds Vue.js frontend
+- `integrate-archipelago.sh` - Combines everything into ISO
+- `build-custom-iso.sh` - Updated to include backend/frontend
+
+## What Will Happen Next
+
+Once the backend compiles:
+
+1. **Integration Build**
+   ```bash
+   ./integrate-archipelago.sh
+   ```
+   This will:
+   - Take the compiled backend binary
+   - Take the built frontend files
+   - Create new ISO with both included
+   - Configure nginx to serve UI
+   - Create OpenRC service for backend
+   - Set up auto-start on boot
+
+2. **Result**
+   You'll have: `archipelago-3.19-hp-prodesk-x86_64.iso`
+   
+   Which includes:
+   - Alpine Linux 3.19 base
+   - Podman + container tools
+   - Archipelago backend (`/usr/local/bin/archipelago`)
+   - Archipelago web UI (`/usr/share/archipelago/web/`)
+   - nginx configured on port 8100
+   - Backend API on port 8101
+   - Auto-start services
+   - DHCP networking
+
+3. **Boot Experience**
+   - Boot from USB
+   - Login as root
+   - Run `/media/cdrom/archipelago/install.sh`
+   - System installs everything automatically
+   - Reboot
+   - Backend starts automatically
+   - Web UI accessible at `http://device-ip:8100`
+
+## Features in the Complete OS
+
+### Container Management
+- Install containerized apps (Bitcoin Core, LND, etc.)
+- Start/stop/remove containers
+- View logs and status
+- Resource monitoring
+
+### Web UI
+- Dashboard with system stats
+- App marketplace
+- Container app management
+- Settings and configuration
+- Onboarding flow
+
+### Backend API
+- RPC endpoints for all operations
+- WebSocket for real-time updates
+- Container orchestration
+- App manifest parsing
+- Dependency resolution
+
+### Security
+- Rootless Podman containers
+- Separate user account (archipelago)
+- SSH access
+- Firewall ready
+- Encrypted secrets storage (planned)
+
+## File Sizes
+
+- **Base ISO**: 208 MB (Alpine + packages)
+- **Backend binary**: ~50-80 MB (estimated, includes all deps)
+- **Frontend**: ~14 MB
+- **Final ISO**: ~300 MB (estimated total)
+
+## Next Session
+
+If the backend build completes:
+1. Run `./integrate-archipelago.sh`
+2. Flash to USB
+3. Boot on HP ProDesk
+4. Test full system
+
+If it doesn't complete:
+- Resume the build
+- Docker container maintains build cache
+- Won't need to recompile dependencies
+
+## Build Time Estimates
+
+- Frontend: 3-4 seconds ✅ DONE
+- Backend (first time): 5-10 minutes ⏳ IN PROGRESS
+- Backend (incremental): 30-60 seconds
+- ISO integration: 2-3 seconds
+- Total: ~10-15 minutes for complete build
+

+
+**Current Time**: Building backend...  
+**Estimated Completion**: 5-10 minutes from start
