What's Wrong?

As of 2.1.107, verbose mode no longer shows the contents of written files inline (screenshot below). This is a major issue when using Claude Code for real-time pair programming. Seeing all diffs in the terminal, including for new files, is essential. This change means every new file has to be opened manually to review. That's fine if you're running CC as a background agent, but not for pair programming.

This kind of over simplificaiton doesn't make sense for a verbose mode.

What Should Happen?

Show proper diffs (i.e. _all_ file changes) in verbose. I.e. how it's been working until the last version.
