Refactor home scripts to be wrappers around component scripts

- Simplified build.sh to call individual component build scripts
- Refactored run.sh to call component run scripts with live log display
- Each service gets color-coded prefix ([SUPER], [OSIRS], [COORD])
- Run script keeps running and displays interleaved logs from all services
- Added proper signal handling for graceful shutdown of all services
- Updated README with new architecture and usage examples
