Hermes bec6413fc5 feat: system-monitor - C++23 terminal TUI system monitor with FTXUI 
Real-time terminal system monitoring tool in C++23:
- CPU usage per-core with color-coded progress bars
- Memory (RAM + swap) with full breakdown
- Load average, uptime, process list (top 20 by RSS)
- FTXUI terminal UI with 1-second auto-refresh
- /proc filesystem parsing with clean RAII design
- Full test coverage: 11 tests + benchmarks with Catch2 v3
