Enhance README and build scripts for hardware-specific optimizations

- Updated README.md to clarify development setup for macOS/Docker and added production build instructions for specific hardware.
- Introduced new build scripts for optimized OS images targeting Start9 Server Pure, HP ProDesk 400 G4 DM, and Dell OptiPlex.
- Enhanced Dockerfile to specify platform compatibility and improved Alpine profile for Archipelago builds.
- Updated configuration files and init scripts to support new hardware profiles and ensure proper service management.
