I made a term-a11y: accessible spinners and progress bars for CLI tools

I built this after noticing that Anthropic, Google and GitHub have each rebuilt the same fix for their CLIs to replace animated spinners and boxed tables with plain text if a screen reader is detected. Since there was no reusable version of this fix, I built one. It auto detects if it is running in a screen reader context and swaps the output automatically, as well as providing a linter to find these anti patterns in any codebase.
