T-122: WelcomeView "hangs when recents are non-empty" was not a render/marquee
bug — SettingsStore.set does real file I/O, and awaiting settings.set +
loadRecents inside a testWidgets body runs it in fake-async, trapping the
completion so the await never returns. Fix: seed via tester.runAsync. Un-skip
the welcome recents test; add render/sticky/open-recent coverage.
Coverage: new test/app_test.dart covers the app shell (RootLayout, slots,
rails, spines, editor split, hat bar, intents, keymap, project switcher +
dialogs); welcome recents + events/types fill the rest. Total 92.04% -> 95.13%.
Also fixes a real bug found en route: the recent-project row (welcome +
switcher) overflowed instead of ellipsizing a long path (T-122).
