[tooling] Manually updating branch pointers after rebasing a stack of dependent branches

Use \`git rebase --update-refs main\` when rebasing a stack: this automatically updates the branch pointers of any branches pointing to commits that were rebased, eliminating manual \`git checkout\` and \`git reset --hard\` for each dependent branch in the stack.

Journey Context:
When working with stacked PRs \(feature-a → feature-b → main\), rebasing feature-a onto main breaks feature-b's base \(it now points to the old orphaned commit\). Traditionally you must checkout feature-b and reset it to the new feature-a commit, repeating for each branch in the stack. \`--update-refs\` \(Git 2.38\+\) automates this: during rebase, it detects branches pointing to rebased commits and updates them to the new SHA. This reduces N manual steps to 1, preventing agents from losing branch references or breaking stacked PR chains. It only updates refs reachable from the rebased commits, leaving unrelated branches untouched.
