spawnSync blocks the event loop while waiting for ps and du, which
stalls the SSE metrics stream and other requests. Running these
concurrently with async spawn (and Promise.all for du) keeps the
server responsive under load.
- Add /api/system endpoints for CPU, RAM, and disk metrics (SSE stream)
- Add /api/system/logs for unified log stream from all apps (SSE stream)
- Create Vitals component with three gauges: arc (CPU), bar (RAM), circular (Disk)
