android: the sweep — what thirty rounds left behind, and the byte that hid a file from grep

Nothing here changes what the phone does, and the walks are untouched on
purpose: they are the guard, not the subject. Out go nine imports no file
ever names again, two things nothing in src, tests, crates or src-tauri
has ever referenced — `forgetAccount` in the Soulseek store, whose Sign
out row calls `disconnect`, and `isLossless` in util.js — and two CSS
rules no markup can reach, `.cardpad` and `.iconbtn.liked`; `stamp` and
`fmtCount` had each been written twice word for word, so both bodies move
into util.js unchanged and four screens gain a name on an import line they
already had. The byte is in player.svelte.js, where the play-history key
joins artist and title on a NUL that was written into the source as the
character itself rather than as the escape catalog.svelte.js already uses
— that made the file non-text, so every grep of it since has answered
"Binary file matches" and shown nothing. One line is added rather than
removed: `.mini .mini-lane { width: auto }` reads exactly like the strays
and is the only thing keeping the lane from coming out 32px wider than the
strip it was cut for, so it now says so — and `.feat`, declared twice in
shell.css with different values, is left alone, because untangling that
moves pixels and this round may not. A tenth dead import is missing from
that first list on purpose: Sheet.svelte's `import * as api` is a namespace
import, the one shape Rollup cannot shake, so its reason was the bundle
rather than drift and it went out with the round before.
