Disk Analyzer

# Description

Disk Analyzer is a Linux disk I/O monitoring CLI tool that reads statistics directly from /proc/diskstats and /sys/block. Built in C++23 with CLI11 for argument parsing, nlohmann_json for structured JSON output, and spdlog for logging. It provides detailed disk statistics (completed reads/writes, transferred sectors, I/O times), device information (model, size, HDD/SSD type), real-time bandwidth monitoring with IOPS calculation, and output in table or JSON format. The RAII architecture with std::expected provides robust error handling without exceptions. Includes complete unit, integration, and benchmark tests with Catch2.
