devin-ai-integration[bot] 0a5d52478c docs: update package logos with theme-aware dark/light variants (#1462)
## Summary

Replace the old `logo-circle.png` in the CLI, JS SDK, and Python SDK
READMEs with the new E2B wordmark logos that adapt to GitHub's theme
setting.

Each package README now uses a `<picture>` element:
```html
<picture>
  <source media="(prefers-color-scheme: dark)" srcset=".../logo-white.png">
  <source media="(prefers-color-scheme: light)" srcset=".../logo-black.png">
  <img alt="E2B Logo" src=".../logo-black.png" width="200">
</picture>
```

- **Light theme** → black logo (`logo-black.png`)
- **Dark theme** → white logo (`logo-white.png`)
- **NPM/PyPI** (no `<picture>` support) → falls back to the black logo
via the `<img>` tag

New logo assets added to `readme-assets/`: `logo-black.png`,
`logo-white.png`.

Includes a patch changeset for `@e2b/cli`, `e2b` (JS SDK), and
`@e2b/python-sdk`.

What is E2B?

E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.

Run your first Sandbox

1. Install SDK

npm i e2b

2. Get your E2B API key

  1. Sign up to E2B here.
  2. Get your API key here.
  3. Set environment variable with your API key
E2B_API_KEY=e2b_***

3. Start a sandbox and run commands

import Sandbox from 'e2b'

const sandbox = await Sandbox.create()
const result = await sandbox.commands.run('echo "Hello from E2B!"')
console.log(result.stdout) // Hello from E2B!

4. Code execution with Code Interpreter

If you need runCode(), install the Code Interpreter SDK:

npm i @e2b/code-interpreter
import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()
const execution = await sandbox.runCode('x = 1; x += 1; x')
console.log(execution.text)  // outputs 2

5. Check docs

Visit E2B documentation.

6. E2B cookbook

Visit our Cookbook to get inspired by examples with different LLMs and AI frameworks.
