…tation (#17723)

Adds support for Google GenAI manual instrumentation in
@sentry/cloudflare and @sentry/vercel-edge.
To instrument the Google GenAI client, wrap it with
Sentry.instrumentGoogleGenAIClient and set recording settings.

```
import * as Sentry from '@sentry/cloudflare';
import { GoogleGenAI } from '@google/genai';

const genAI = new GoogleGenAI({ apiKey: 'your-api-key' });
const client = Sentry.instrumentGoogleGenAIClient(genAI, { 
  recordInputs: true,
  recordOutputs: true 
});

// use the wrapped client with models api
const model = client.models.generateContent({
  model: 'gemini-1.5-pro',
  contents: [{ role: 'user', parts: [{ text: 'Hello!' }] }]
});

// or use chat functionality
const chat = client.chats.create({ model: 'gemini-1.5-flash' });
const response = await chat.sendMessage({ message: 'Tell me a joke' });
```

)

This may flake, so just using any available port instead.

Closes #17716

…17712)

We often store isolationscopes on spans via `setCapturedScopesOnSpan` and
retrieve them via `getCapturedScopesOnSpan`. This change wraps the
scopes in `WeakRef` to attempt fixing a potential memory leak when spans
hold on to scopes indefinitely.

The downside is spans might end up with undefined scopes on them if the
scope was garbage collected, we'll have to see if that's an issue or
not.

[Gitflow] Merge master into develop

This PR adds the following:
- an E2E test case for Nitro `$fetch` requests
- Upgrading the Nuxt 4 version (previously in alpha)
- Deleting the `app.vue` file as this is not needed when using the
`app/pages` directory (following the [Nuxt
docs](https://nuxt.com/docs/4.x/guide/directory-structure/app/app))

meta(changelog): Update changelog for 10.14.0
