SysDashboard

# Description

SysDashboard is a Linux system monitoring dashboard that reads hardware statistics directly from /proc. Developed in C++23 with FTXUI for the interactive TUI interface, nlohmann_json for structured JSON output, and spdlog for logging. It displays per-core CPU usage with colored progress bars, system memory (total, used, available, swap), disk throughput (R/W KB/s and IOPS), network traffic (RX/TX in kbps and packets/sec), load average, uptime and CPU core count. Includes JSON mode for integration with external scripts and monitoring tools. The RAII architecture uses std::expected for error handling without exceptions. The TUI interface uses FTXUI ScreenInteractive with 1-second refresh via background thread and PostEvent re-rendering.
