🎨 Palette: Use Erase in Line ANSI escape sequence for dynamic text updates

[EiJackGH]

💡 What: Replaced hardcoded space padding in dynamic CLI text lines with the \033[K ANSI escape sequence (Erase in Line).

🎯 Why: When replacing text "in-place" using carriage returns (\r), using a standard number of trailing spaces to overwrite prior longer text strings is brittle and can lead to trailing text artifacts or misaligned outputs. The \033[K sequence is universally supported, cleaner, and strictly clears everything to the end of the line.

📸 Before/After: Lines like std::cout << "\rStarting in " << i << "... " << std::flush; now read std::cout << "\r\033[KStarting in " << i << "... " << std::flush; removing the need for \rGO! \n.

♿ Accessibility: Makes terminal output visually cleaner, improving the developer/user experience.
