Minor internal rework of how the transcript view memoizes and hides advisor tool result messages

What

The internal memoization logic behind the message-list view was regenerated, including the logic that folds or hides assistant messages whose first piece of content is an advisor tool result, when certain verbose/other display flags are turned off.

Why

This is an internal rendering optimization; the evidence doesn't indicate a change in what is actually shown to users beyond this existing hide/fold behavior.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtWhether this changes what appears on screen, versus being a purely internal memoization detail, isn't clear from the evidence.
