Feature Request: Allow adding directories from arbitrary paths on local computer

[hugoriosbrito]

What feature would you like to see?

I would like Kimi CLI to support adding entire directories from any location on the user's local computer, not just from the current working directory. This would allow users to organize, access, and manage files from multiple locations, making the tool more flexible for projects and workflows that span various folders.

Additional information

Currently, users are limited to adding directories that are within or relative to the current working directory. Enabling directory selection from any local path would streamline multi-project workflows and improve usability for those who keep resources in different locations across the computer.
