fix(2.03.33): stable window size between pages, fix benchmark-ww controls clipped

- Stack.set_homogeneous(True) keeps dialog height constant when switching pages
- Benchmark WW paned position raised 260→390 so all TTS config, engine
  checkboxes, wakeword/samples/run fields are visible without scrolling
- Both benchmark pages disable their page-level ScrolledWindow so the
  Paned fills the viewport rather than growing to natural height

 ## [Unreleased]
 
+## [2.03.33] - 2026-06-10
+
+### Fixed
+- **Settings window no longer resizes when switching pages.** Added
+  `Gtk.Stack.set_homogeneous(True)` so the dialog always allocates the
+  maximum page height, preventing the window from growing or shrinking
+  as pages are visited.
+- **Benchmark — Wakeword: "Engines to test" section no longer hidden.**
+  The paned divider position was raised from 260 to 390 px so all TTS
+  config fields, the engine checkboxes, wakeword model selector, sample
+  count, and run button are fully visible without scrolling. Both
+  benchmark pages also disable the page-level `ScrolledWindow` so the
+  paned correctly fills the viewport height rather than expanding
+  past it.
