[tooling] How to rebase a stack of dependent Git branches without manually updating each one

Use \`git rebase --update-refs \` to automatically update all descendant branches when rebasing a stack, or set \`rebase.updateRefs = true\` in config for default behavior

Journey Context:
Developers maintaining feature stacks \(branch A → branch B → branch C\) traditionally had to manually rebase C onto B and B onto A after any rebase of A. This is error-prone and tedious. --update-refs \(added in Git 2.38\) creates a .git/rebase-merge/update-refs file tracking the old→new SHA mappings for all branches in the rebased sequence, automatically rewriting the refs. Without this, agents waste tokens on complex rebase scripts or manual steps; with it, entire stack rebases become atomic operations.
