crush CLI — `~` expansion strips Windows backslashes from hook paths
On Windows, crush's hook-runner expands `~` to `$HOME`, MSYS converts the Unix-style path back to `C:\Users\...`, and the bundled mvdan/sh POSIX emulator then unescapes the backslashes (`\U`, `\j`) before bash ever sees them. Hook paths arrive mangled as `C:Usersjrnew/.config/crush/hooks/...` and silently exit 127.
