## 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`.
