// report::detail::ReplaceFolders (runtime/report/scrub.h), what ScrubHome
// does to the text of a bug report before it leaves the machine. Header
// only. From the repo root:
//   clang++ -std=c++20 -O2 -Iruntime tests/scrub_test.cpp -o build/scrub_test
//   build/scrub_test
// - POSIX (HOME as "~"): whole folders only, as since 2026-09-28: not
//   /home/deck2, not the tail of /mnt/home/deck; the longest folder first
//   (HOME and its real path).
// - Windows (the user's folder as %USERPROFILE%): the same rule, letters in
//   either case, \ and / alike, a backslash escaped (\\) too, the 8.3 name
//   as a folder of its own; a folder never matches inside a longer name.
