Issue: Regarding the installation error of promptfoo
Root cause: Environment Incompatibility

Hi @mldangelo ,
I always run the command 'npm install - g promptfoo' on my Mac, but it always includes the following error:

This problem has been bothering me all day, can you help me solve it

This code is always incorrect, do I need anything？
`  const HOST = getEnvString('PROMPTFOO_CLOUD_API_URL', 'https://api.promptfoo.app');
  try {
    // Call the the agent helper to evaluate the results of the provider
    const testAnalyzerResponse = await fetch(`${HOST}/providers/test`, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        config: providerOptions,
        providerResponse: result.raw,
        parsedResponse: result.output,
        error: result.error,
        headers: result.metadata?.headers,
      }),
    });
`

Hi @wk1583241477! For your first error: 

It looks like you are running into a compilation error with the `better-sqlite3` dependency on macOS. This is a common issue that happens when C++ development tools aren't properly configured. The error `'climits' file not found` typically means the C++ headers are missing. Try:

```bash
  xcode-select --install
```

  If they're already installed, you might need to reset:

```
  sudo xcode-select --reset
```

For your second error 

The issue in the snippet you showed is missing backticks for the template literal:

  Incorrect:
```js
  const testAnalyzerResponse = await fetch(${HOST}/providers/test, {
```
  Correct:
```js
  const testAnalyzerResponse = await fetch(`${HOST}/providers/test`, {
```

The backticks are needed to create a template literal that allows variable interpolation with ${HOST}`.


If this doesn't work, please send me an email (michael @ promptfoo.dev) and we can find some time to debug together.  I am going to close the issue but please feel free to comment / re-open if you would like more help here. 

About my second error,
I'm sorry for i didn't make myself clear。
Because i run  red team  on page，it always error，i look the code，error code is my second error。
And error message is "Error running redteam: Error: Unable to proceed with test generation: Network error: Request timed out after 5000 ms
URL: https://api.promptfoo.app/health
Please check your API configuration or try again later.
[POST /providers/test] Error calling agent helper
error: fetch failed
providerOptions: {"id":"http","label":"111","config":{"useHttps":false,"url":"http://localhost:11434/api/chat","method":"POST","headers":{"Content-Type":"application/json"},"body":"{\"model\": \"qwen3:0.6b\", \"prompt\": \"{{prompt}}\",\"stream\":false}","validateStatus":"","transformResponse":"(json,text) => json.response || text"}}".


And i run "Option 2: Run Directly in Browser", error message is
