Ports the three sections the tab was missing, against the Slint implementation rather than invented: the section rails, the cards, and the mix landing page with its navigation seam so back/forward behave. The mixes reuse the shared crates for their requests -- the Slint app already makes them, so nothing new talks to Qobuz here. Also carries the qt-run.sh portability work needed for the Mac mini: `free`, `nproc`, `pgrep` and `timeout` all differ or are simply absent on BSD/macOS. Two of those bit during the first Mac build. `pgrep` exits 1 when it matches nothing -- the normal case -- and under `pipefail` that killed the script before a single line of output, which reads exactly like a build that did nothing. And `timeout` does not exist on macOS at all, so the smoke produced a one-line log over which the grep cheerfully reported "0 QML complaints": a test that never ran, rendering as a pass. The smoke now fails outright on a log that short. cc

// Tracks tab body (LocalLibraryView.slint:1317) — the SERVER-PAGINATED flat
|
|
// list. This is the surface that froze the Slint build at 16k tracks: the
|
|
// model is never the whole table (500 rows per page, appended within 600px
|
|
// of the tail — the Slint's own trigger distance at :1442) and the ListView
|
|
// only ever instantiates its window.
|
|
//
|
|
// Grouping (off / album / artist / name) inserts 32px header rows, so the
|

// model is an entry array — { t: 0, label } | { t: 1, row, n } — exactly as
|
|
// the collection does it, keeping ONE windowing ListView with variable row
|

// heights instead of a Repeater per group.
