Using Execution Plans in Effect Typescript for More Ergonomic Code

const executionPlan = ExecutionPlan.make({ provide: Gemini_2_5_Flash_Lite }, { provide: Gemini_2_5_Pro });
const ModelFallback = Layer.effect(
    AiLanguageModel.AiLanguageModel,
    Effect.gen(function* () {
        return {
            generateObject: flow(AiLanguageModel.generateObject, Effect.withExecutionPlan(executionPlan)),
            generateText: flow(AiLanguageModel.generateText, Effect.withExecutionPlan(executionPlan)),
            streamText: flow(AiLanguageModel.streamText, Stream.withExecutionPlan(executionPlan))
        };
    })
);
