Subject: [PATCH] +semver:patch - Speed up Engine.Tests and fix missing [Test]
 attribute

Remove ProcessorCountParallelLimit from TUnit.Engine.Tests assembly - these
tests are I/O-bound subprocess launches, not CPU-bound, so capping parallelism
at processor count unnecessarily serialises ~119 tests into sequential batches.

Also add missing [Test] attribute to TimeoutTests1.Test() which was silently
not running.
