Batch 1 of the scripts/ root cleanup: the closure scripts no runtime entry, other script, workflow, deploy file, ops doc or quality gate reaches, with their 11 test files (30 cases). Their references/ outputs stay. Scripts still imported elsewhere, named by the gate, or listed in archived reference indexes are kept. Root budget 452 -> 441.
