| description | Rebase a feature worktree on main/master, resolve conflicts, ff-only merge into the trunk worktree, then rebase feature on updated trunk. |
Regroup
main/master here means the trunk git branch.
Run from a non-trunk worktree.

Guardrails
- Stop on unexpected dirty state.
- Ask for semantic conflict choices.
- Never non-ff merge into trunk (
main or master).
- Never push/force-push unless asked.
- If no trunk worktree exists, ask for path.
