vc=64 fixed RelatedRow's empty-metadata bug. ChannelVideoRow and
ResultRow had the same shape problem AND duplicated duration:
- ChannelVideoRow: showed 'N views · 0:42' which doubled with
the VideoThumbnail's bottom-right duration badge. Stripped
the duration text, added uploadDateRelative. Now reads
'N views · 2 days ago' matching YT's channel page format.
- ResultRow: same duplicate-duration. Same fix. Search results
now show 'N views · 2 days ago' under the uploader line.
All four video-row composables (FeedRow, RelatedRow,
ChannelVideoRow, ResultRow) now use the same leading-separator
buildString pattern: 'piece [· piece]*' that gracefully composes
whatever fields are populated. No more empty metadata lines, no
more duplicate duration.
