[FEATURE] Allow users to add custom directories outside Cowork home folder to workspace restrictions

Problem Statement

On macOS, many users store projects on external drives (like /Volumes/ExternalDrive/Projects). Currently, Claude Cowork Desktop only allows workspaces within the user's home directory, making it impossible to work with projects on external volumes.

Proposed Solution

Add a configuration option (e.g., in settings or a config file) to allow users to whitelist additional directories beyond the home folder.

This would be similar to how VS Code and other editors handle directory access permissions, providing flexibility while maintaining security through explicit user consent.

Alternative Solutions

allow users to just use additional directories beyond the home folder.
