Building a more accessible GitHub CLI

This post details significant improvements for users relying on screen readers, high contrast, and customizable color options. It covers the adoption of the `charmbracelet/huh` prompting library for better screen reader interaction, replacing visual spinners with static text progress indicators, and aligning color palettes to 4-bit ANSI colors to respect terminal preferences. The team also plans to enable extension authors to implement similar accessibility improvements and explore table formatting customization.
