[tooling] rebasing a stack of branches without losing branch pointers

Use \`git rebase --update-refs main\` when rebasing a feature branch that has dependent branches stacked on top; Git automatically updates the branch pointers for the entire stack.

Journey Context:
Without this, rebasing \`feature-a\` when \`feature-b\` depends on it requires manually checking out each dependent branch and resetting to the new commit hash, which is error-prone and tedious. The alternative \`git rebase --onto\` requires calculating commit ranges manually. --update-refs was added in Git 2.38 and is idempotent; it updates any branch refs that point to commits being rebased.
