Shared TabChipStrip replaces the plain Rows in libraries/downloads/live
TV app bars (and live TV's hand-rolled scroll wrapper); chips center
themselves on focus so d-pad reaches off-screen tabs.
Album/artist downloads expand to tracks with pinned parent metadata,
aggregate progress, container deletes with reference-counted album
covers, and a Music tab on the downloads screen with fully offline
album playback. Home rows include music libraries (fixes plex hub
items being filtered to video types) and audio playlists join
download/sync rules.
Poster images are decorative (the card exposes one merged node), and
the default per-child AutomaticKeepAlive/_SelectionKeepAlive/
IndexedSemantics wrappers are inert here — no keep-alive clients or
SelectionArea exist. The semantics phase ran ~9ms every frame on TV
devices with an accessibility service; it scales with node count.
