[BUG] Dangerous assumptions made in regards to the work tree branching model

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

The default work tree makes dangerous assumptions silently.

• The work tree was created automatically without prompting
• It silently branched off main, not the user's current branch
• There was no warning or confirmation
• For teams with protected branch workflows, this default is dangerous

What Should Happen?

Assumptions about a user's Git flow absolutely should not be made - especially silently.

Many teams have protected work flows and never do feature or bug work off of the main branch.
