Remarks

Starting in TinyBDD v1.1, all BDD test methods are automatically optimized via source generation by default. Use this attribute to opt-out and use the standard pipeline instead.

**When to opt-out:** - When using IStepObserver or IScenarioObserver (not yet supported in generated code) - When using BeforeStep/AfterStep hooks - When using complex ScenarioOptions features - When debugging and you want to step through the standard pipeline - When you encounter generator limitations

Example: 

[DisableOptimization]  // Uses standard pipeline
public async Task ScenarioWithObservers()
{
    // This will use the standard pipeline with full features
    await Given("start", () => 1)
         .When("add", x => x + 1)
         .Then("equals 2", x => x == 2);
}

**Performance trade-off:** The standard pipeline adds ~500-800ns overhead per step but provides full extensibility. Generated code runs in ~20-50ns per step.
