Conversation
Previously, `gh stack sync` gated the cascade rebase on whether trunk or stack branches were fast-forwarded during the current run. This meant that if the user had already updated trunk locally (e.g., `git pull`), sync would skip the rebase entirely even though stack branches hadn't been rebased onto the current trunk. This change: - Adds `stackNeedsRebase()` to detect stale branches regardless of whether trunk was updated in this run - Extracts shared helpers (`fastForwardTrunk`, `cascadeRebase`, `resolveOriginalRefs`) from duplicated code in sync.go and rebase.go into utils.go, reducing ~450 lines of duplication - Fixes rebase.go to skip queued branches (was only skipping merged), consistent with sync's behavior via `IsSkipped()` - Refactors rebase --continue to reuse the shared cascade helper Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
