// list children in their own order, so entries sort by virtual path and emit in
// reverse: a code-point path sort is a pre-order walk (`/` precedes any name char,
// so a directory always precedes its children) and its reverse is a valid
// children-first order — deterministic across every backend, matching GNU
// exactly on a single-child chain. Mirrors Python `removal_lines`.
