Subject: [PATCH] Surface content_types on discover state for the client to
 build a dynamic Type filter

Kotlin's readDiscoverCatalogFilters effect now returns a contentTypes
list (distinct catalog types found across installed addons, e.g.
movie/series/anime), but the effect completion flows back through the
engine's own discover state before Kotlin ever sees it again. Added
content_types to DiscoverState and store it in the completion handler
for readDiscoverCatalogFilters, preserving it across a fresh discover
dispatch the same way catalogs/genres already are.
