Subject: [PATCH 01/11] build(sdk): move to .NET SDK 10.0.401 and refresh CI
 actions

Pin the SDK to 10.0.401 with an explicit workloadVersion 10.0.401.1 so
the workload set no longer drifts independently of the SDK. Every
workflow now reads the same root global.json through setup-dotnet's
global-json-file input instead of repeating a 10.0.3xx channel.

SalmonEgg/global.json only duplicated the Uno.Sdk pin; MSBuild picks the
nearest file, so the two copies could silently split the GUI project and
src/tests onto different SDKs. It is removed and all directories share
the root file.

The stable Apple workload for 10.0.401 requires Xcode 27, so the iOS
gates move to the xcode-27 runner (public preview) and the Windows jobs
to windows-2025-vs2026 for Visual Studio 18.9.3+.

Actions are bumped to checkout v7.0.1, setup-dotnet v6.0.0,
upload-artifact v7.0.2, download-artifact v8.0.2 and codeql-action
v4.38.2, all pinned by SHA. The published bridge gate moves to
acpremote 1.10.0. Docs (README zh/en, BUILD_GUIDE, release-guide) and
the workflow guard tests follow the new pins.

Subject: [PATCH 02/11] chore(deps): bump Graph, MSAL, Windows App SDK 1.8 and
 test packages

- Microsoft.Graph 6.7.0 -> 6.8.0
- Microsoft.Identity.Client(.Extensions.Msal) 4.90.0 -> 4.90.1
- Microsoft.WindowsAppSDK 1.8.260804001 -> 1.8.260921001; WinUI stays at
  1.8.260803003, the exact version this meta-package pins in its nuspec
- Porta.Pty 2.2.2 -> 2.2.3, Websocket.Client 5.5.0 -> 5.5.1
- coverlet.MTP 10.0.1 -> 10.1.0, Moq 4.20.72 -> 4.21.0

Windows App SDK 2.x is intentionally deferred until Uno 6.7 and MSIX
packaging are validated on it.

Subject: [PATCH 03/11] fix(sdk): drop the global.json workloadVersion pin

sdk.workloadVersion makes the MSBuild workload resolver require that
exact workload set, so every project fails with MSB4242 on a fresh runner
that has not installed it, including jobs that need no workload at all.
It also rejects the --skip-manifest-update flag our workload install
steps use. Workload manifests follow the SDK feature band again, as on
main; BUILD_GUIDE records why the field is intentionally absent.

Subject: [PATCH 04/11] build(ios): raise the minimum iOS version to 15.0

Uno.Sdk 6.7.30 still defaults SupportedOSPlatformVersion to 14.2 for iOS,
but the Xcode 27 Apple workload (Microsoft.iOS.Sdk 27.0) that ships with
the 10.0.401 SDK band fails the build below 15.0. iOS 15 runs on exactly
the devices iOS 14 did, so no supported hardware is dropped.

The xcode-27 runner image does not register Simulator with LaunchServices,

Contents/Applications/DeviceHub.app instead, so the path lookup from the
previous commit still found nothing. Accept either layout and list the
apps actually present when neither exists.

Subject: [PATCH 08/11] test(gates): sample the stalled iOS product before
 cleanup

On the Xcode 27 / iOS 27 simulator the product logs its startup marker and
then nothing else, while the same flow on iOS 26.5 logs the next startup
step within two seconds. The app log cannot say which thread or frame is
stuck. When the gate fails after install, take a host stack sample of the
product process, the device's unified log for it, and any crash report
before cleanup terminates it, and upload them.

Subject: [PATCH 09/11] fix(ci): pin the iOS workload set that runs on GA Xcode
 26.6

The 10.0.401 feature band ships two workload sets. 10.0.401.0 carries the
Apple workload 26.5.10318, which requires Xcode 26.6; 10.0.401.1 moves to
27.0.10722, which requires Xcode 27. Installing without a version picked
the newest set and forced both iOS jobs onto the xcode-27 public-preview
image, where the iOS 27 simulator took over five minutes to install the
app and then wedged simctl and the product's own startup.

Pin --version 10.0.401 on the two iOS workload installs, the same
per-job pin main used with 10.0.300.3, and return to the GA macos-26
image with its Xcode 26.6. The guard test now requires the pin.

Subject: [PATCH 10/11] Revert "build(ios): raise the minimum iOS version to
 15.0"

That floor was only required by the Xcode 27 Apple workload (27.0), which
the iOS jobs no longer install; the pinned 26.5 workload accepts Uno.Sdk's
14.2 default, as on main.

This reverts commit 63b291af17a95f5075d12f6e086a0bd389b9ff7c.

Subject: [PATCH 11/11] fix(gates): size the iOS XCUITest budget for Xcode 26.6

On macos-26 with Xcode 26.6 the installed-product test passed, but
xcodebuild test-without-building took 458 s end to end (main on Xcode
26.5: 241 s), overrunning the 420 s wait. Raise it to 600 s and give the
reverse verification matching headroom.

Cleanup then crashed with EPERM from killpg: macOS reports that, not
ESRCH, when the process group holds only zombies. Treat it as gone.
