9039451e2f [Quick Accent] Migrate UI to WinUI 3 (#48891) 
## Summary of the Pull Request

Migrates the **Quick Accent (PowerAccent)** module's UI from WPF
(`System.Windows.*`) to **WinUI 3 (Windows App SDK)**, following the
pattern used by other migrated modules (ImageResizer, PowerDisplay). The
accent selector is now a self-contained WinUI 3 app
(`PowerToys.PowerAccent.exe`) shipped under `WinUI3Apps`, and
`PowerAccent.Core` is UI-framework-agnostic.

## PR Checklist

- [x] Closes: #48889
- [x] **Communication:** Tracked task (#48889) agreed with core
contributors
- [x] **Tests:** Added/updated and all pass — new
`PowerAccent.Core.UnitTests` (21 tests for the positioning / DPI math);
existing `PowerAccent.Common.UnitTests` unaffected
- [x] **Localization:** No new localizable end-user strings — new
accessibility metadata uses non-localized
`AutomationProperties.AutomationId`, and the window title is the brand
name `"Quick Accent"` (literal, matching ColorPicker)
- [x] **Dev docs:** Updated `doc/devdocs/modules/quickaccent.md`
- [x] **New binaries:** Added on the required places
- [x] [JSON for
signing](https://github.com/microsoft/PowerToys/blob/main/.pipelines/ESRPSigning_core.json):
the `WinUI3Apps\` PowerAccent payloads are listed in
`ESRPSigning_core.json`
- [x] [WXS for
installer](https://github.com/microsoft/PowerToys/blob/main/installer/PowerToysSetup/Product.wxs):
no manual `Product.wxs` entry — the self-contained `WinUI3Apps` output
(exe + `.pri` + Windows App SDK runtime) is harvested by the
`WinUI3ApplicationsFiles` glob (same as ImageResizer)
- [x] [YML for CI
pipeline](https://github.com/microsoft/PowerToys/blob/main/.pipelines/ci/templates/build-powertoys-steps.yml):
no change needed — `PowerAccent.Core.UnitTests` is discovered by the
existing `**\*UnitTest*.dll` VSTest glob
- [x] [YML for signed
pipeline](https://github.com/microsoft/PowerToys/blob/main/.pipelines/release.yml):
covered by `ESRPSigning_core.json`; no `release.yml` change needed
- [ ] **Documentation updated:** N/A — internal UI-framework migration
with no user-facing behavior change

## Detailed Description of the Pull Request / Additional comments

The migration spans three areas (tracked in #48889):

**UI (WPF → WinUI 3)**
- `PowerAccent.UI` is now a WinUI 3 app shell (custom `Program.Main`,
`WindowsPackageType=None`, `WindowsAppSDKSelfContained=true`).
- The accent selector is a non-activating `TransparentWindow` overlay
shown with `SW_SHOWNA` (never steals focus). It is made always-on-top
only while shown — the WinUIEx `WindowEx.IsAlwaysOnTop` property is
toggled `true` on show / `false` on hide in `OnChangeDisplay` (matching
the WPF original's `Topmost = isActive`), so the dormant,
never-destroyed overlay does not pin a discrete GPU awake on
hybrid-graphics laptops (issue #34849 / PR #41044).
- The accent "pill" selection visual is reproduced with
`VisualStateManager` (WinUI 3 has no `Style.Triggers`).
- **WinUI 3 gotcha:** x:Bind on a Window-rooted XAML initializes only on
`Window.Activated`, which never fires for this `SW_SHOWNA` overlay — so
the selector calls `Bindings.Update()` after `InitializeComponent()`;
without it the `ListView` renders empty.
- **Theme:** the long-lived, never-activated process follows the system
app theme automatically — `App.xaml` leaves `Application.RequestedTheme`
unset, so WinUI re-resolves the `{ThemeResource}` brushes (and retints
the acrylic) on a live light/dark switch with no manual `ThemeListener`
needed.
- **Layout parity with the WPF original:** the bar width hugs its
content (`itemCount × 48`, clamped to the monitor width — computed, not
measured, to avoid a racy `ListView` measure), and each cell pins
`MinWidth=48` (WinUI's `ListViewItem` defaults to 88, which would
otherwise leave wide gaps).
- **Accessibility:** UIA window name + `AutomationId`s on the character
list and description.

**Dependency**
- `PowerAccent.Core` no longer depends on WPF — it raises events and
takes an injected UI-thread marshaller.
- WinForms `SendKeys` → `SendInput` (CsWin32 P/Invoke); WPF-UI (Lepo)
removed; language data moved to the UI-/WinRT-agnostic
`PowerAccent.Common`.
- MVVM via CommunityToolkit.Mvvm with `[ObservableProperty]` **partial
properties** (WinRT-correct, clears MVVMTK0045).

**CI / Build / Installer**
- Signing config, WinUI3Apps glob harvest, and the new unit-test project
— see the checklist above.

## Validation Steps Performed

- **Build:** `x64 Debug` builds with **0 warnings / 0 errors**.
- **Unit tests:** `PowerAccent.Core.UnitTests` — **21/21 pass** (9
anchor positions × DPI 1.0/1.5/2.0, the offset and negative-origin
monitors, caret centering + edge clamping + flip-below).
- **XamlStyler:** `PowerAccentXAML/MainWindow.xaml` passes the passive
format check (CI mode).
- **Manual (single monitor, Top-center, light theme):**
  - Accent popup appears with the full accent list rendered.
- Bar hugs the characters and is centered; cell spacing matches the WPF
original.
- Switching the system theme (light/dark) is followed live by the popup.
- With `show_description` enabled, the description row is wide (≥600px)
and readable, with the accent bar centered above it.
- **Remaining manual validation** (tracked in #48889): multi-monitor,
per-monitor DPI, all 9 `toolbar_position` values, and high-contrast
theme.

af45c3ec7c Add press-and-hold activation mode to Quick Accent (#48937) 
## Summary of the Pull Request

Adds an opt-in **press-and-hold** activation mode to Quick Accent, like
iOS / macOS: hold an accent-capable letter (e.g. `a`) and after a short,
configurable delay the accent picker opens automatically — no separate
trigger key (Space/arrows) required.

This is purely additive. The existing trigger-key modes (`Left/Right
arrow`, `Space`, `Both`) and all serialized settings values are
unchanged.


https://github.com/user-attachments/assets/faec298c-e42c-4fd1-84bd-6e74d1b481a0


### What it does

- Holding a letter types the base letter immediately, then arms the
picker. After the **Hold duration** (default **500 ms**) the toolbar
appears.
- Navigate the options with the arrow keys / Space, then **release the
letter** to insert the selected accent (it replaces the base letter).
- A quick tap types just the letter. Holding and releasing without
selecting leaves the base letter as-is.
- `Ctrl` / `Alt` / `AltGr` / `Win` + letter combinations are left
untouched, so shortcuts like `Ctrl+A` still work.

## PR Checklist

- [ ] **Closes:** N/A — feature enhancement (happy to link a tracking
issue if one is preferred)
- [x] **Communication:** Discussed direction with maintainers;
coordinated with #48891 (see below)
- [ ] **Tests:** No automated tests added — the activation decision
lives in the C++ low-level keyboard hook and isn't reachable from the
existing managed unit-test project. Validated manually (steps below).
Open to guidance on the preferred test surface.
- [x] **Localization:** All new end-user strings are in
`Settings.UI/Strings/en-us/Resources.resw` with translator comments.
- [x] **Dev docs:** `doc/devdocs/modules/quickaccent.md` updated with
the new mode.
- [x] **New binaries:** None.
- [x] **Documentation updated:** Dev docs updated; public Learn docs can
follow once shipped.

## Detailed Description of the Pull Request / Additional comments

- **`PowerAccentKeyboardService` (C++ hook):**
- Append `PressAndHold` to the internal `PowerAccentActivationKey` enum
(value `3`, appended to preserve serialized `0/1/2`).
- Add a `holdDuration` setting and `UpdateHoldDuration(Int32)` to the
WinRT projection (`.idl`).
- In `OnKeyDown`, arm the picker on the held letter itself; the base
letter still types on first press and auto-repeat is swallowed (reuses
the existing `m_toolbarVisible` repeat guard from #36853).
- In `OnKeyUp`, use the hold duration as the minimum-hold release
threshold for this mode (trigger modes keep using `inputTime`).
  - Modifier guard: Ctrl/Alt/AltGr/Win do not arm the mode.
- **Settings model (`Settings.UI.Library`):** append `PressAndHold` to
`PowerAccentActivationKey`; add `hold_duration_ms` (`IntProperty`,
default 500). Existing `settings.json` without the field falls back to
the 500 ms default.
- **`PowerAccent.Core`:** read and forward the hold duration to the
hook, and use it as the popup delay when `PressAndHold` is active.
- **Settings UI:** add the **"Press and hold the letter"** activation
option and a **"Hold duration (ms)"** control that is shown only when
that mode is selected.

### Enum sync note

`PowerAccentActivationKey` exists in both the C++ hook and the managed
settings library and is kept in sync by integer value. `PressAndHold`
was **appended** (never reordered) so existing serialized settings
(`0/1/2`) keep their meaning.

### Coordination with #48891 (Quick Accent WinUI migration)

This lands as its own atomic change on `main`. The overlap with the
in-progress WinUI migration (#48891) is tiny: only `PowerAccent.cs`'s
mode-aware popup delay (a single `Task.Delay` line). The C++ hook,
settings enum/model, and Settings UI are not touched by #48891, so it
can rebase onto this with minimal effort.

## Validation Steps Performed

- Built the full chain in `Debug|x64`:
- `PowerAccent.UI.csproj` → rebuilds the C++
`PowerAccentKeyboardService` projection (incl. `UpdateHoldDuration`) +
`PowerAccent.Core` + `Settings.UI.Library`. **0 errors.**
- `PowerToys.Settings.csproj` → Settings UI XAML / ViewModel / `.resw`
(XamlIndexBuilder search index regenerated). **0 errors.**
- Manual trial of the running module (`PowerToys.PowerAccent.exe`) with
`activation_key = 3`:
- Hold `a` → base letter types immediately; picker opens after ~500 ms;
arrows/Space navigate; releasing inserts the accent (replacing the base
letter).
- Quick tap → base letter only. Hold + release without selecting → base
letter remains.
  - `Ctrl+A` / `Alt`+letter unaffected.
