Added an inline math calculator to the list command. Typing = followed by a math expression (like =5+3*2) evaluates it live in the autocomplete suggestions using meval. Integer results display without decimal places, and invalid expressions show an error inline. It’s a small quality-of-life feature that saves opening a separate calculator.

Also fixed a CRLF line ending issue that was breaking the Docker build on Linux, added a .gitattributes to enforce LF endings, and deduplicated shortcuts that appeared multiple times from overlapping scan directories.
