Hidden Files Not Detected: ls Fails to List Dot Files and Directories

Bug Description
Claude uses ls to search the filesystem, which means it often misses hidden files and folders. Hidden files and folders are not only common, they are built-in elements of the Claude Code system (e.g. .claude/ folder) Claude should use ls -la by default

This is also a problem with the @ file/folder reference. It doesn't include hidden files and folders in the auto-complete.
