Cursor CLI @ path autocomplete should support paths outside current workspace

Feature request for product/service

Cursor CLI

Describe the request

Currently the Cursor CLI does not autocomplete files outside of the current workspace. It would be helpful to have @ autocomplete for other paths, for example when pulling in external documents or screenshots.
Repro steps:

  1. Open the Cursor CLI in any directory: cd /tmp && cursor-agent
  2. Use the @ path to auto-complete something like: Read the document at @/home/foo

I’d like to see all items starting with foo* (foobar, foobaz, fooqux) under /home/, similarly to how typing @foo would auto-complete such contents in the current workspace. This example uses an absolute paths, but relative paths (@../../foo.txt) would also be helpful.
