feat: detailed system boot logs (kernel, CPU, mem, disk, services)

start-server.sh now outputs:
- System info: kernel, arch, CPU, memory, disk
- Network interfaces
- Each service start with [OK]/[FAILED] status
- Service summary table (PIDs + ports)
- Package counts (base vs current)
- Full process listing
- All output to stderr for HF runtime logs
