- Add iftop as runtime dependency in package.nix and flake.nix - Modify SystemMetrics to calculate network throughput (bytes/second) - Track previous network stats in MQTT client state for throughput calculation - Update Home Assistant discovery to show RX/TX throughput sensors - Replace cumulative byte counters with real-time throughput metrics - Add proper throughput calculation with time-based differentials This provides much more useful real-time network monitoring compared to ever-increasing cumulative byte counts. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
