Cuesheet v0.13.4

New & improved

• "End" (and "Up next") now work reliably on a paused class — the real fix. The 0.13.3 attempt deferred the tap by one main-actor turn, which still raced the menu dismissal on a real device (the "only works sometimes" you saw). The run-mode ⋯ is now a plain button opening a standard action sheet, and the End/Up-next confirmation is raised only *after* that sheet closes — so there is no menu-dismissal transaction left to drop it, paused or playing. Verify on device: tap End on a paused class.
• The run-mode ⋯ now matches the builder's exactly. They were two different frameworks — the builder's is a native nav-bar button (iOS's circular chrome), run mode's was a hand-drawn symbol with no chrome. Run mode now renders the same iOS glass circular button, held to the 44pt hit floor.
