Fixed in commit 18c2ba2. The issue was that the Laravel Prompts Spinner suppressed output during execution. Theme suggestions are now stored during the spinner and displayed after it completes.

Before:

   Building vendor/Nema (1 of 1) ... failed
(No suggestions shown)

After:

   Building vendor/Nema (1 of 1) ... failed

   [ERROR] Theme vendor/Nema is not installed.
   Did you mean:
     - Vendor/name
     - Vendor/theme
     - Vendor/custom

Suggestions now work correctly in both verbose and non-verbose modes.
