chore(docs): reconcile to WPF-only after WinUI 3 was abandoned

- Fix TeamsISO.Windows.slnf — drop the dangling
  src/TeamsISO.App.WinUI/TeamsISO.App.WinUI.csproj entry whose project
  doesn't exist in the .sln (broke the build on main).
- Archive the abandoned WinUI 3 artifacts under docs/archive/:
  * 2026-05-12-winui3-migration.md (the nine-phase migration plan)
  * TeamsISO.App.WinUI.Probe/ (the bootstrap diagnostic console)
  * work-log-2026-05-12-winui3.md (the overnight session log)
- README — drop the "in-flight WinUI 3 replatform" status block;
  state that the v2 redesign landed in WPF and link the shape brief.
  Keyboard shortcuts table picks up Ctrl+K, Ctrl+T, and the digit
  hotkeys that already shipped.
- CHANGELOG — replace the WinUI-3-flavoured "Ground-up GUI redesign"
  block with a v2 Studio Terminal entry that names Task 39 + Task 40
  as landed. De-dupe the May 2026 batch: the second "Quick-join Teams
  meeting from URL", "IN-CALL bar surfaces Teams meeting state", and
  "Auto-launch Teams + auto-hide windows" bullets were verbatim repeats
  of earlier entries; kept the first occurrence.
- NEXT_STEPS.md — rewrite to reflect that Task 39 (participants table
  v2) and Task 40 (Ctrl+K palette) both shipped; v1.0 cut is now
  gated only on MSI signing + real-meeting smoke pass.
- DESIGN.md — small WPF-isms: WinUI 3 composition layer →
  WPF's; Segoe Fluent Icons phrased without the "WinUI 3's
  bundled" qualifier; migration boundary rephrased to "rewrites
  MainWindow.xaml + Themes/*" instead of "everything in Views/".
- .gitignore — ignore the .claude/ session metadata dir so it doesn't
  show up as untracked on every dev checkout.

Build + tests verified before commit: 0 errors, 0 warnings; 160 tests
pass (56 App + 104 Engine, filter Category!=ndi&requires!=ndi).

 ## [Unreleased]
 
-### Added — Ground-up GUI redesign (started 2026-05-12)
+### Added — v2 "Studio Terminal" GUI (2026-05-13)
 
-After greenlighting a from-the-scratch redesign and an explicit WinUI 3
-replatform target, the May 2026 batch is followed by a major
-restructuring of the host UI. Highlights:
+The May 2026 ground-up redesign — explicit anti-reference to "the v1
+GUI screamed AI made it" — landed on the WPF host
+(`src/TeamsISO.App/`). The shape brief lives at
+`docs/shapes/2026-05-13-teamsiso-v2-studio-terminal.md`. An earlier WinUI
+3 replatform was scoped on 2026-05-12 and abandoned in favour of doing
+the redesign in WPF (activation blockers + redundant work given the
+shared view-model surface). The abandoned migration plan + bootstrap
+probe are archived under `docs/archive/`.
 
 - **PRODUCT.md** + **DESIGN.md**: impeccable context for the redesign.
   Solo broadcast operator at 1:50am is the canonical persona; "vibe-coded
   GUI" is the explicit anti-reference. Tokens cover dark + light palettes
   with context-aware accent split (cyan surface fill stays bright in
-  both modes; cyan-as-text darkens to #0E7C82 on light for AA contrast).
-- **WinUI 3 host scaffold** as `src/TeamsISO.App.WinUI/` coexisting with
-  the existing WPF host. WindowsAppSDK 1.6 LTS, unpackaged mode, win-x64
-  pinned RID, custom Bootstrap-aware `Program.Main`, post-build runtimeconfig
-  patch to drop the .NET-SDK-implicit `Microsoft.WindowsDesktop.App`
-  framework reference (WinUI 3 doesn't use it).
-- **Redesigned MainWindow**: 64px rail with brand mark + nav +
-  engine-status puck; 44px custom title bar absorbing live pills
-  (session timer · REC count · disk free) + theme toggle; section header
-  with single Primary CTA + Secondary actions; participants list
-  (ItemsRepeater stub pending DataGrid migration) at 64px row height
-  with cyan-left-border active-speaker treatment; conditional slim
-  in-call control bar; 32px status bar.
-- **ThemeManager service** holds the user theme preference
-  (System / Dark / Light), resolves via UISettings.GetColorValue when
-  System, broadcasts changes so the AppWindow title-bar buttons stay
-  in sync with the visual tree.
-- **Settings drawer** that slides in from the right (220ms ease-out-quart)
-  with five tabs (Appearance / Routing / Display / Control / Advanced).
-  Appearance tab includes the theme tri-state picker + an accent palette
-  peek. Replaces the WPF host's 380px permanent settings panel.
-- **Help / About / Onboarding** as ContentDialog-based surfaces. Help
-  is the keyboard shortcut cheat sheet; About has Wild Dragon mark +
-  version + quick-access folder shortcuts; Onboarding is three numbered
-  steps for first launch (Install NDI Runtime / Enable Teams NDI / Pick
-  transcoder topology) with "Don't show again" defaulted on.
-- **Interactive HTML preview** at `docs/preview/redesigned-mainwindow.html` —
-  faithful single-file render of the WinUI 3 XAML with theme toggle and
-  drawer interaction, so stakeholders can see the redesign before the
-  WinUI 3 build is feature-complete.
-- **Migration plan** at `docs/superpowers/plans/2026-05-12-winui3-migration.md`
-  with nine phases (scaffold / shell / activation / VM wiring / DataGrid
-  / secondary windows / hardening / tests / retire-WPF) and a risk
-  register flagging fallback paths.
-
-The WPF host (`src/TeamsISO.App/`) is unchanged and remains the shipping
-build until the WinUI 3 build passes a real-meeting smoke test. The
-view-model layer is unchanged so the WinUI 3 host will reuse it via
-ProjectReference once view-model wiring lands (Phase 4 of the plan).

-2. **System theme follow** — open Windows Settings → Personalization → Colors → "Choose your mode" → flip between Dark and Light. TeamsISO should track the OS automatically (default preference is `System`).
-3. **Settings drawer** — click the header gear icon. 420px drawer slides in from the right with OUTPUT / NETWORK / APP tabs. Esc or click-scrim dismisses.
-4. **Transport strip** — should show the session timer when at least one ISO goes live, and the PART/LIVE counts always.
