Fix missing RateTolerance assignment in test execution

[Claude]

Changes proposed in this pull request:

• Add missing RateTolerance = e.RateTolerance assignment in Test.cs:436

The ProcessEvents() method was not transferring the user-configured RateTolerance value from EventSetting to TestVariable, causing it to default to 0 during test execution while the other four tolerance/timeout values (ErrorTolerance, DwellTime, Timeout, Interval) were correctly assigned.

TestVariable testVariable = new()
{
    Setpoint = e.Value,
    ErrorTolerance = e.ErrorTolerance,
    RateTolerance = e.RateTolerance,  // Added
    Interval = new TimeSpan(0, 0, Convert.ToInt32(e.Interval)),
    Timeout = new TimeSpan(0, 0, Convert.ToInt32(e.Timeout)),
    DwellTime = new TimeSpan(0, 0, Convert.ToInt32(e.DwellTime))
};
