Fix documentation: Update TestContext API from context.Result to context.Execution.Result

[Copilot]

Documentation used the deprecated direct context.Result property access instead of the current context.Execution.Result API, and incorrectly referenced TestStatus enum instead of TestState.

Changes

Updated four documentation files to use the correct API:

Before:

if (context.Result?.Status == TestStatus.Failed)
{
    await CaptureScreenshot(cancellationToken);
}

After:

if (context.Execution.Result?.State == TestState.Failed)
{
    await CaptureScreenshot(cancellationToken);
}

Files Modified

• docs/docs/test-lifecycle/cleanup.md - After hook example
• docs/docs/advanced/test-variants.md - Property-based testing shrinking pattern
• docs/docs/advanced/extension-points.md - Event receiver examples (2 locations)
• docs/docs/advanced/performance-best-practices.md - Test metrics tracking example

All documentation now correctly accesses test results via the ITestExecution interface as context.Execution.Result?.State.

if (TestContext.Current?.Result?.State == TestState.Failed)
