vc=82 — subscription-feed enrichment via lightweight stream_metadata

Browse source 
enrich_feed_item now calls the new strawcore stream_metadata() path (Android
/player + videoDetails read only) instead of the full stream_info. The full
path ran the JS sig/nsig deobf, an extra WEB /player metadata round-trip, the
iOS client, and stream/manifest/caption extraction — then kept only view_count
+ duration_seconds. Those two come from the same videoDetails the lightweight
path reads (populate_microformat never touches them), so the values are
identical; the feed just stops paying for the discarded work — ~one heavy
round-trip dropped per enriched item per refresh.

FFI surface (enrichFeedItem -> EnrichedFeedMetadata) unchanged. Needs
strawcore 30f24d2 (pushed first; CI clones strawcore main).
