## Message

```
agent: Make branch diff completion use same default branch as branch diff action (#52223)

## Context

Before this change the branch diff would compare with local main instead
of upstream main. This causes confusion because it's a different diff
than the branch diff action would show users, and cause agents to
potentially review a much larger diff then it has too.
