fix: show tool name instead of bundle name on AI feature install prompt

The install prompt and error messages were showing the underlying AI
bundle name (e.g. "Background Removal") instead of the actual tool name
(e.g. "Passport Photo"). Now the UI shows the correct tool name and
description while still installing the correct bundle behind the scenes.

Closes #130
