feat: add system monitor panel (btop-style) (#455)
* feat: add system monitor panel with live CPU, memory, disk, and GPU metrics New btop-inspired monitoring page in the OBSERVE sidebar group. Polls /api/system-monitor every 2s and renders rolling Recharts area charts for CPU/memory/GPU and progress bars for disk usage. * feat: add network I/O monitoring to system monitor panel Add live network throughput (rx/tx bytes/sec) as a dual area chart. API returns cumulative byte counters per interface (stateless), frontend computes rates from deltas between 2s polls. Supports Linux (/proc/net/dev) and macOS (netstat -ib). * feat: add top processes list to system monitor Shows top 8 processes by CPU usage in a compact table with CPU%, Mem%, and RSS columns. Color-codes high usage values. Uses ps on both Linux and macOS with fallback for platforms without --sort support. * fix: normalize process CPU% to 0-100 and filter out ps itself CPU% from ps is per-core (e.g. 200% on 4 cores), now divided by core count to show total system percentage. Also filters out the ps command that briefly appears while collecting process data. --------- Co-authored-by: Dan <github@bookkept.com.au>
