fix: operator permission check always triggering + typos

[fix2015]

Found a logic bug in the operator permission check — the condition was:

```js
if (operator === Operator.LocalBrowser || Operator.LocalComputer)
```

This always evaluates to true because `Operator.LocalComputer` is a non-empty string on its own. So the permission dialog was firing for every operator type, not just local ones. Added the missing `operator ===` comparison.

Also fixed a few other things while I was in there:

• `Object.keys(settings)` check in Settings was always truthy since arrays are truthy — added `.length > 0`
• "Vision-Lanuage Model" → "Vision-Language Model" in both package.json files
• "lenght" → "length" in a browser debug log
• "Get Start" → "Get Started" in the settings UI button
