Proc Monitor

# Description

Proc Monitor is a Linux system TUI dashboard that reads statistics directly from the /proc filesystem. Built in C++23 with FTXUI for the interactive TUI, nlohmann_json for structured JSON output, and spdlog for logging. Provides per-core real-time CPU usage with colored progress bars, system memory (total, available, used, swap), load average (1/5/15 minutes), active processes, uptime, and core count. Includes JSON mode for script integration and external monitoring. The RAII architecture with std::expected provides robust error handling without exceptions. The TUI uses FTXUI ScreenInteractive with second-by-second updates via a background thread and PostEvent.
