Test and document which terminal emulators work well with KTech

Remember to test at high FPS (e.g. 144) and resolution, and resizing behavior. Maybe write a terminal tester that rapidly shifts colors.

Known terminals that work well:

• Konsole

Known terminals that have issues:

• VSCode's internal terminal renders colors incorrectly
• Windows Console and WSL had flickering (could be outdated as that wasn't tested since the Windows port)
