fix: list_files recursive mode now works correctly for hidden directories

- Fixed ripgrep exclusion pattern from `!**/.*//**` to `!**/.*/**`
- Hidden directories (like .git/) now appear in recursive listings but their contents are excluded
- Contents of hidden directories are only shown when explicitly targeting that directory
- Prevents context window overflow from massive hidden directories like .git/
- Maintains consistent behavior: show directory exists, avoid flooding with contents

Fixes #2992
