[DOCS] Label which interface supports the /permissions Auto mode editor

### Documentation Type

Unclear/confusing documentation

### Documentation Location

https://code.claude.com/docs/en/auto-mode-config#edit-rules-from-permissions

### Section/Topic

Edit rules from /permissions

### Current Documentation

The section instructs users to run /permissions and select the Auto mode tab.

### What's Wrong or Missing?

The section does not identify which interface supports this editor. The Desktop documentation says /permissions is unavailable in the Code tab and directs users to settings files or the standalone CLI.

### Suggested Improvement

Label the interfaces that support this editor and add a cross-link to the Desktop instructions for editing settings files or using the standalone CLI.

### Impact

Low - Minor confusion or inconvenience

### Additional Context

_No response_

Start with the “Edit rules from /permissions” section at https://code.claude.com/docs/en/auto-mode-config#edit-rules-from-permissions, then read the related Desktop instructions for editing settings files or using the standalone CLI. Update the section to label which interfaces support the editor and add the cross-link; done when the interface limitation and alternatives are clear.
