Detailed Description

LogMonitorDisplay formats and accumulates multiple log streams into a structured, bordered terminal display. It supports drawing boxes around log content, truncating long lines while preserving ANSI colors, and optionally stripping colors if the output terminal doesn't support them.

Example usage:

LogMonitorDisplay display(80); // 80 columns wide
display.DrawReport(launcher_source, 20);
display.DrawReport(kernel_source, 40);
LogMonitorDisplayResult result = display.Finalize();
std::cout << result.output << std::flush;
