A new helper formats describe_type results for files that are unread or unreadable
What
A new function handles the case where a describe_type result includes a type file. It now distinguishes between a file that is unread or unreadable, showing a reason for that, and a file with normal readable content, before falling back to the previous formatting behavior for other cases.
Why
This gives a clearer, explained result when a type file can't be read, instead of presenting it the same way as normally readable content.
