text trigger attach file not working

[DimitriGilbert]

The FileControlModule's handleFileAttach method attempts to read local files using fetch('file://...'). This fails in browser environments due to security policies that block fetch requests to the file:// protocol, resulting in a network error and preventing file attachment.
