feat(queue): two-level deque model — PLAY prepends, add appends, last-track-end empties

Fixes five queue bugs: Playlist relabel, last-track-empties, dormant-seed-from-player on first add, immediate panel reactivity, and front/back deque semantics. Adds JumpTo for row jumps.

                @* Fixed (embed) queue panel (§4 / AC5). A release embed shows the up-next inline below the
                   controls as a read-only list (Editable=false → no drag handles, no remove buttons; C3).
                   Jump-to-track is still allowed (OQ2) — routed through the same OnQueueJump as the docked
-                   overlay, which calls PlayRelease (clearing IsArmed if the embed was armed-but-not-started).
+                   overlay, which calls JumpTo (moves the pointer and streams the row, clearing IsArmed).
                   Gated on ShowFixedPanel so a single-track embed (empty queue) stays panel-free (UC6). The
                   Queue button collapses/expands this panel (OQ1 Option A); collapse hides it and posts the
                   shrunken height to the host iframe. *@
