Research direction

Start at the gh stack adopt command and trace how it assigns a branch's parent. Check the parent chain before accepting the adoption; done means an adoption that would make a cycle is rejected as an error.

Written by the indexing model from the issue text.

Description

bug

It's theoretically possible to use gh stack adopt to create a cycle wherein branch a's parent is branch b; branch b's parent is branch c; and branch c's parent is branch a.

Let's prevent that; introducing a cycle should be an error.
