[JS] Log level change + repetitive 'Shutting down all Genkit servers...' message

[sevseux]

Describe the bug

Hi, it's not a bug but why the log recently changed from debug to info ? (inside this PR)

genkit/js/genkit/src/genkit.ts

Line 856 in 94ea90c

logger.info('Shutting down all Genkit servers...');

✔  functions: Loaded functions definitions from source: api, backend
>  Shutting down all Genkit servers...
>  Shutting down all Genkit servers...

To Reproduce

I currently use genkit without external server and Flows but inside my firebase functions running in Emulator.
I don't need to firebase init genkit

const { genkit } = require("genkit");
const { openAI, gpt4o } = require("genkitx-openai");

const genkitInstance = genkit({
    plugins: [
        openAI({
            apiKey: process.env.GENKIT_OPENAI_API_KEY,
        }),
    ],
    model: gpt4o,
});

const { output } = await genkitInstance.generate({
    prompt: "Say hi",
});

Expected behavior

Avoid getting "Shutting down all Genkit servers..." for every reload during development
