yonlu 7a1412383f perf(library): send the track list as a dictionary-encoded column table
GetTracks answered with one JSON object per track: 20.5 MB at 26k
tracks, ~350 bytes a row of repeated key names, four cover URLs that
are identical across an album, and the album, artist and genre strings
repeated on every track. Encoding it was ~170 MB of transient Go
allocation, and parsing it the WebView's memory peak.

GetTrackTable replaces it: one array per column, every repeated
string stored once and sent as an index, genre lists interned, and only
the fields the Tracks view reads. LastPlayed and the three larger cover
tiers are left to the details dialog, which now fetches whole tracks by
path. Each row still goes through trackFromRow, so this is an encoding
of the one projection, not a second one. 167 bytes a track against 929
in the test library; a Go test holds it under a quarter of the object
encoding, and a Vitest test reads the Go columns and the generated
Track interface and fails if they drift.

An empty library is now an empty table rather than the "no tracks in
library" error the old binding returned.

The rest of #186's second table, and one thing it could not have said.

    .section-toggle          187x15  autotag
    .folders-menu-trigger     32x18  autotag
    .back-button              32x32  artist-details
    Requests / Downloads tabs 85x34, 96x34
    .search-mode-tab          89x26, 79x26  explore
    explore search input     325x18  in a 36px box

**back-button was six controls, not one.** The issue names it in
artist-details because that is the view the sweep opened; the same
declaration is byte-identical in artist-details, genre-details,
playlist-details, smart-playlist-details, explore-artist-details and
explore-album-details, 32px in all six. So it is styles/back-button.
css.ts now, adopted by each, and a source sweep fails on a seventh
copy -- because the failure this invites is not a size changing, it is
somebody adding a detail view and writing `.back-button` out again,
which no device sweep would catch for the same reason this one did
not. That is icon-language.test.ts's shape, and the argument for it
here is the inverse of the column arrows': one declaration covering
36 controls is cheap to fix, and six declarations of one control are
six chances to miss five.

It is a real 44px box rather than padding with the width handed back:
a detail header runs no fit pass, and this button has a visible
background, so a hit area larger than the circle would be a control
bigger than it looks. The size is #55's, reached there for the same
reason -- "the way out is 44px on a phone".

**The explore search box was two faults.** The row was 36px *and* the
input inside it was 18, so eight pixels at each edge were not a target
at all: a tap near the top of the box landed on the container and did
nothing. The container is 44 and the input stretches to it.

**The Downloads tabs take padding rather than a min-size**, because
the mark for the selected tab is its bottom border -- a min-size
centres the label and leaves the underline 10px beneath it.

page-action-check-now (113x29) is in that table and is not here: it is
a PageAction, so #195 raised it with the rest of the header's actions
and touch-targets.test.ts already covers it.

**The Downloads tabs needed a min-size as well as the padding, and CI
is what said so.** Padding alone made them 44px on this machine and
**43px in the container**: the total is 13 + 13 + 2 + whatever line box
the font gives 13px text, and ubuntu:24.04's is a pixel shorter than
Arch's. A height computed from a font's line box is not a height you
control -- which is #195's "stated as a property on the strength of one
engine" one layer down, in the same PR that recorded it. The padding
stays, because it is what keeps the underline against the label; the
min-size is the floor.

Caught by the new test rather than by a person, which is the half of
this that worked.

Verified on the device, sweeping each view the way the issue was
filed: explore, downloads, autotag and artist-details now report
**one** control under the floor apiece, and it is the skip link, which
#186 already ruled out as keyboard-only. .search-mode-tab 89x44 and
79x44, the search input 325x44, the Downloads tabs 85x44 and 96x44,
.section-toggle 174x44, .folders-menu-trigger 44x44, .back-button
44x44.

All 12 new tests fail on main, the source sweep naming all six copies.
make ui-test 1041 pass; make e2e 236 pass on chromium, which is half
an answer -- CI had the other half, and used it.

Closes #186
