android: the repair sheet, browse, every long-press sheet, You's last sections, the lyrics tools — and the walk's audio check made honest

The playlist repair (Find a local match: the library searched by the
row's name, a pick relinks it through playlist_relink_item; an unknown
row takes the track's identity). A peer's sheet on the raw results (play
or save the folder, browse their files, message, buddy) and the Browse
screen — the hub's Browse tab: a user's whole share with sizes and totals,
a folder played or saved whole; a share can hold thousands of folders, so
it filters and renders 80 at a time. "Look up a user" on Community →
Buddies. The sheets the phone lacked: a queue row's (Play now, Move to
next, Remove from queue), a catalog song's, a catalog card's and the
record page's own, a raw file's (in the results and in Browse), a room
name's, a buddy's, the now-playing Save (the desktop's Save menu for a
streamed track or record). The artwork viewer with pinch zoom, one layer
the back gesture peels. Search's recent searches and its spelling
suggestion from the names this phone knows. You → Streaming, Downloads,
Sharing, Lyrics, Album artwork, and Clear play history; a record's
Re-fetch the cover. The lyrics tools on the sheet's face: the offset
nudged and kept per track, another LRCLIB candidate chosen, the lookup
forgotten and done again (lyrics.svelte.js, shared by the face and the
lyrics sheet).

The harness: every CDP call times out and the reload step re-attaches
(a WebView that stopped answering hung a walk for ten minutes); the
audio check counts SoulStream's own tracks' underruns from the mixer dump
instead of the thread-wide counters that any app's notification moves —
the afternoon's "dropouts" were other apps' sounds, and the browse of a
49,544-file share measured at zero; __settle resets every tab to its root
through the nav; an adb step kind; the walks cover all of the above on
the mock and on the phone.
