Public re-export of the internal humanize helper so other aggregator
modules (in particular article-html.ts) can derive the same display
title from a file stem when no curated title is available. Keeping the
single canonical implementation here avoids duplicate humanisation
rules drifting across modules.
Parameters
stem: string
File stem (e.g. electoral-cycle-methodology)
Returns string
Humanised title (e.g. Electoral Cycle Methodology)
