"""Regression guard for #5559 — the KEYWORD index (load_personal_index, which
PersonalDocsManager.refresh_index builds from) must skip hidden dirs, hidden
files, and junk dirs at ANY depth, the same as the vector index. Both walkers
share one pruning helper (src/index_walk) so they cannot drift again.
