Reduce thread count from 8 to 4 and iterations from 3 to 2 in the thread safety test. The test was consistently taking ~31-32s, just over the 30s CI global timeout, causing all core pipeline runs to fail. The reduced workload (4x2=8 parallel calls) still validates thread safety via the barrier synchronization while completing well within the timeout.

Reduces the workload of a flaky thread-safety test to avoid exceeding the CI 30-second global timeout.
Changes:
- Lower
threadCountfrom 8 to 4 - Lower
iterationsPerThreadfrom 3 to 2
Explain why threadCount and iterationsPerThread are kept low, referencing the 30s CI global timeout from GlobalTimeoutTearDown. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

This seems brittle, as the overall load on a CI run is going to influence the timing. Depending on what else gets pulled into pullrequest you'll still potentially exceed the timeout.
For something non-deterministic like this, we may want to consider putting in a local cancellation token that triggers after ~25 seconds and does an ignore assert.
It's not ideal, but basically defaults to "we couldn't complete this test" instead of failing the run.

Azure.Security.CodeTransparency - Fix flaky thread safety test
Fixes #59267
Problem
The
VerifyTransparentStatement_ThreadSafety_ParallelCallsShouldNotFailtest has been consistently failing across all recent core pipeline runs (pipeline #1180). The test runs 8 threads × 3 iterations = 24 crypto-heavy operations, taking ~31-32 seconds — just over the 30-second CI global timeout.This is blocking the entire core pipeline on
main.Fix
Reduced the test workload from 8 threads × 3 iterations to 4 threads × 2 iterations. The test still validates thread safety via barrier synchronization ensuring all threads start simultaneously. With the reduced workload, the test completes in ~244ms locally.
