Hermes WebUI Desktop v0.3.3

Fixed

• macOS: app froze ("crashed") every time a new tab was opened. Cmd+T
  built the window fine, but the native tab attach (addTabbedWindow) ran
  inside the event loop's dispatch, where AppKit may force the other tab's
  window to redraw synchronously — and that redraw re-enters the windowing
  layer's non-reentrant lock, deadlocking the main thread on itself. The app
  froze instantly and forever (no crash report — it never crashes, it hangs;
  confirmed by macOS hang diagnostics on v0.3.1 and v0.3.2). The freeze only
  triggers when the two windows' sizes differ, which is why default-size dev
  windows masked it and real resized windows hit it 100% of the time. Tab
  attach (and the Cmd+N tabbing-mode dance) now runs via the GCD main queue —
  outside the event dispatch — and Cmd+T/Cmd+N window creation runs inline on
  the main thread on macOS, like the original prototype. Verified live: tab
  attach plus continued main-thread heartbeats on the previously-freezing
  setup.
