Run directory slug (e.g. breaking-run192)
Target language code
{ title, description, runId } — title is always non-empty
(falls back to a humanized slug when no run-type prefix matches);
description may be an empty string for unknown run-type slugs or
when the descriptions table has no entry for a recognized type.
runId is the run-index tail ('192') or the raw slug when no
run-type prefix matched.
Resolve a localized title + description for a daily analysis run.
