Under automation read roots, `ui.inspect` kept a folder preference whose
stored value was readable even when the trimmed path the app uses was
not: ` /outside/fonts` reads as a name in the working folder, while the
app uses `/outside/fonts`. A folder preference now stays only when both
forms are readable. A reply string is decoded for path matching only when
it holds a `%XX` escape, so a string such as `width="100%"` is no longer
decoded and thrown away. The library list line in the progress doc now
states when a hidden library's `loaded/<file name>` id moves.
