* fix: correct utility process exit code on Windows

On Windows, process exit codes are 32-bit unsigned integers (DWORD).
When passed from Chromium to Electron as a signed int and then
implicitly converted to uint64_t, values with the high bit set
(e.g., NTSTATUS codes) undergo sign extension, producing incorrect
values.

Cast the exit code to uint32_t before widening to uint64_t to
prevent sign extension and preserve the original Windows exit code.

Fixes #49455

* feat: support notification priority on Windows

Add Windows notifications support urgency/priority levels.
This maps the existing `urgency` option (previously Linux-only) to
Windows toast notification priorities:

- 'critical' maps to ToastNotificationPriority_High, which sorts the
  notification above default-priority items in Action Center.
- 'normal' and 'low' both map to ToastNotificationPriority_Default.

Note that on Windows, 'critical' priority does not prevent the toast
from being auto-dismissed. Users should additionally set `timeoutType`
to 'never' for that behavior.

feat: add nativeTheme.shouldDifferentiateWithoutColor on macOS

Adds nativeTheme.shouldDifferentiateWithoutColor on macOS that maps to
NSWorkspace.accessibilityDisplayShouldDifferentiateWithoutColor. If true,
the user has indicated that they prefer UI that differentiates items with
something other than color alone. This is useful for users with color
vision deficiency.

gfx::PNGCodec::Decode() returns a null SkBitmap when it fails to decode
the clipboard contents as a PNG. Passing that null bitmap to
gfx::Image::CreateFrom1xBitmap() triggers a crash.

Return an empty gfx::Image instead, matching the existing null-check
pattern in skia_util.cc.

The weak persistent tracking the OffscreenReleaseHolderMonitor was tied
to the texture object, but the release() closure holds a raw pointer to
the monitor via its v8::External data. If JS retained texture.release
while dropping the texture itself, the monitor would be freed on GC and
a later release() call would crash.

Track the release function instead of the texture object. Since the
texture holds release as a property, this keeps the monitor alive as
long as either is reachable.

GetDefaultPrinterDPI() creates a blank GtkPrintSettings and reads
its resolution, which returns 0 for uninitialized settings. With
DPI=0, SetPrintableAreaIfValid() computes a zero scale factor,
producing empty page dimensions that fail PrintMsgPrintParamsIsValid().

Fall back to kDefaultPdfDpi (72) when GTK returns 0, matching the
existing Windows fallback pattern when CreateDC fails.

* fix: hex-encode Windows notification icon temp filenames

NotificationPresenterWin was using SHA1HashString(origin.spec()) directly
as the basename for the temporary PNG written for toast icons.

SHA1HashString returns raw digest bytes, so the generated filename could
contain invalid path characters on Windows. That caused WriteFile to fail
when saving notification icons, which left toast XML without the expected
icon path.

Hex-encode the digest before appending .png so the temporary filename is
filesystem-safe while keeping deterministic naming for a given origin.

The frameNamesToWindow map was a holdover from the BrowserWindowProxy
IPC shim. Since nativeWindowOpen became the only code path, Blink's
FrameTree::FindOrCreateFrameForNavigation resolves named window targets
directly in the renderer, scoped to the opener's browsing context
group. When a matching named window exists, Blink navigates it without
ever sending a CreateNewWindow IPC to the browser, so this map was
never consulted in the legitimate same-opener case.

The only time the map found a match was when two unrelated renderers
happened to use the same target name, in which case openGuestWindow
would short-circuit before consuming the guest WebContents that
Chromium had already created for the new window, leaking it.

Adds a test verifying Blink handles same-opener named-target reuse
end-to-end without any browser-side tracking.
