…P_CRASH after successful runs (#1551)

* Initial plan

* Fix tvOS device communication failures causing false TIMED_OUT and APP_CRASH results

Three layered fixes:

1. DeviceLogCapturer: Add 2-minute timeouts to 'log collect' and 'log show' processes
   in StopCapture() to prevent indefinite blocking when Apple TV device log streaming
   is broken (fixes apple run TIMED_OUT after mlaunch exits with expected code).

2. ResultFileHandler: Add retry with backoff (up to 3 attempts, 5s/10s/20s delays)
   to devicectl file copy in CopyResultsAsync() to handle transient device communication
   errors (com.apple.Mercury.error 1000, RSD error 0xE8000003).

3. TestReporter.ParseResult(): When Success=true was already set by CollectDeviceResult()
   (test run completed via app end signal), but the results file is missing (devicectl
   failed), return Succeeded instead of Crashed. Device communication failure after
   successful test completion is an infrastructure issue, not an app crash.

4. AppTester: Skip crash report retrieval when test run already completed and file copy
   fails, replacing misleading 'app may have crashed' message with accurate warning.

Adds unit tests for retry behavior and the new TestReporter.ParseResult() path.

* Address PR review feedback

- DeviceLogCapturer: Add WaitForExit() flush after timed WaitForExit() to ensure
  async stdout/stderr buffers are fully drained before reading them (both log collect
  and log show processes).
- DeviceLogCapturer: Fix _outputPath cleanup on early-return paths (timeout and
  non-zero exit) by extracting CleanupOutputPath() helper and calling it uniformly.
- ResultFileHandler: Make DefaultRetryDelaysMs private (tests inject via constructor);
  clone the array on assignment to prevent external mutation.
- Integration tests: Update osx.13.amd64.open Helix queue to osx.15.amd64.open.

* Update Simulator.Commands Helix queue from osx.13 to osx.15

The Simulator.Commands.Tests.proj was using osx.13.amd64.open (macOS Ventura 13)
which is the oldest queue. Update to osx.15.amd64.open to align with the other
Apple simulator test projects and dotnet/runtime.

* Update iOS simulator version to 18.1 for osx.15 queue

The osx.15 machines have iOS 18.1 pre-installed. The old 16.4 version
required downloading a 6.18 GB simulator runtime, causing timeouts.

* Use architecture-specific test app bundle for simulator commands test

The non-architecture-specific app bundle (from June 2025) fails to launch
on iOS 18.1 simulators. Update the download URL to use the x64-specific
path which has a newer app bundle (December 2025) that is compatible.

* Use 'apple test' instead of 'install + just-test' in Simulator Commands E2E test

The manual 'install' + 'just-test' flow has a systematic failure on iOS 18.1
simulators (APP_LAUNCH_FAILURE). The 'apple test' command, which handles the
full lifecycle internally, works correctly on the same platform. This change
replaces the failing flow while still exercising 5 manual commands:
simulators install, reset-simulator, device, test (with --device), and uninstall.

The 'just-test' failure on iOS 18.1 should be investigated separately.

* Don't fail test on uninstall after 'apple test' cleanup

The 'apple test' command shuts down the simulator during cleanup,
which causes the subsequent 'apple uninstall' to fail with
PACKAGE_NOT_FOUND. The uninstall is still executed to exercise
the command, but its exit code no longer affects the test result.

Avoid StreamReader.EndOfStream in the async run-log parser.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Make ThreadlessXunitTestRunner platform-generic so it can be used on
iOS/tvOS/Mac Catalyst in addition to WASM. The runner uses reflection-based
test discovery (ThreadlessXunitDiscoverer) which is NativeAOT-compatible,
unlike XUnitTestRunner which depends on XunitFrontController for dynamic
assembly loading.

Changes:
- ThreadlessXunitTestRunner: make ResultsFileName settable, refactor
  WriteResultsToFile to support file-based XML output on non-browser
  platforms while preserving existing WASM behavior
- iOSApplicationEntryPoint: detect NativeAOT via
  RuntimeFeature.IsDynamicCodeSupported and automatically use
  ThreadlessXunitTestRunner when dynamic code is not available

[main] Update dependencies from dotnet/arcade


 - Fix CA2024: Do not use StreamReader.EndOfStream in async methods

Implement the recommendation from https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca2024

 - Merge branch 'main' into darc-main-d6137969-a1fd-4d9c-b794-faea8b997496

 - Merge main and update .NET SDK to 11.0.100-preview.2.26159.112

Merge latest main into the Arcade update PR branch and resolve the
global.json conflict by upgrading the .NET SDK to Preview 2
(11.0.100-preview.2.26159.112). The previous SDK version
(11.0.100-preview.1.26104.118) has a known bug (dotnet/sdk#53101)
where dotnet tool install fails with 'DotnetToolSettings.xml not found',
breaking all Helix E2E tests.

…1563)

The retry logic in GetChromiumDriver only catches TargetInvocationException
when the inner exception is WebDriverException. However, Selenium
4.0.0-alpha05 throws InvalidOperationException (not WebDriverException)
for 'session not created: Chrome failed to start: crashed' errors that
include 'DevToolsActivePort file doesn't exist'.

This means the retry never fires for this common transient failure,
causing intermittent test failures across CI (dotnet/runtime#124438).

Changes:
- Broaden catch to also match InvalidOperationException inner exceptions
- Add 'DevToolsActivePort file doesn't exist' to retryable error snippets
- Detect Windows containers via DOTNET_RUNNING_IN_CONTAINER env var
  for --no-sandbox (/.dockerenv only exists on Linux)

Both Debug and Release matrix legs call CIBuild which includes -publish,
causing both to simultaneously upload PackageArtifacts (e.g.
Microsoft.DotNet.XHarness.CLI.nupkg) to the same AzDO artifact container.
This results in intermittent 'Blob is incomplete (missing block)' errors.

Fix by passing /p:Publish=false for the Debug leg so only the Release
leg publishes packages to artifact storage. The Debug leg still builds,
tests, signs, and packs -- it just skips the artifact upload step.

* Reduce mlaunch default verbosity from 5 to 2

The default verbosity of 5 causes mlaunch to pass five -v flags to
devicectl, producing massive debug output (full device property trees,
connection details, capabilities) that clutters console logs. Reducing
to 2 keeps useful diagnostic info while removing the noise.

* Add NativeAOT xunit test runner with threaded execution

Introduce NativeAotXunitTestRunner that extends ThreadlessXunitTestRunner
with parallel test execution support and file-based result output.
ThreadlessXunitTestRunner uses reflection-based discovery (NativeAOT-safe)
but forces single-threaded execution. The new runner overrides the
configuration to allow parallel test collections since NativeAOT has
threads available.

- Add NativeAotXunitTestRunner extending ThreadlessXunitTestRunner with
  configurable MaxParallelThreads and ParallelizeTestCollections
- Extract virtual CreateConfiguration() and RunnerDisplayName from
  ThreadlessXunitTestRunner for extensibility
- Revert PR #1554 changes to ThreadlessXunitTestRunner, keeping it
  WASM-only as originally intended
- Update iOS and Android entry points to use NativeAotXunitTestRunner
  when RuntimeFeature.IsDynamicCodeSupported is false

* Refactor: extract CustomXunitTestRunner abstract base, rename to ReflectionBasedXunitTestRunner

Address review feedback:
- Rename NativeAotXunitTestRunner to ReflectionBasedXunitTestRunner
- Extract shared reflection-based discovery logic into abstract
  CustomXunitTestRunner base class
- Make ThreadlessXunitTestRunner and ReflectionBasedXunitTestRunner
  concrete implementations of CustomXunitTestRunner

…ch compatibility (#1572)

Define XHarnessNetTFMs centrally in Directory.Build.props so all shipped
packages include net8.0 through net11.0. This ensures downstream repos on
older .NET SDKs (e.g. dotnet/runtime release/8.0-staging, release/10.0) can
consume XHarness packages from main.

The Arcade SDK 11.0 defines NetMinimum=net10.0 and NetPrevious='' (empty),
so projects using only Arcade variables end up with just net10.0 and net11.0.
