[Feature Request] Add command to list auto-rules in .claude/rules directory

Bug Description
Claude created a markdown file in .claude/rules for me, to better work with mermaid diagrams. It recommended placing it there, but I later learned it is an "auto rule" that just gets pulled into context when working with certain file types that have mermaid diagrams. Like you can do with skills and /skills I want to be able to see what "auto rules" like this I have, without having to fish around in Finder or the cli.
