Implement secure cloud sandboxes with E2B (#35)
* chore: rename utils.ts to fileoperations.ts * feat: replace node-pty with E2B sandboxes * added debounced function in the editor * fix: move socket connection to useRef * fix: wait until terminals are killed to close the container * fix: ensure container remains open until all owner connections are closed * fix: sync files to container instead of local file system * fix: set project file permissions so that they belong to the terminal user * fix: use the container URL for the preview panel * fix: count only the current user's sandboxes towards the limit * fix: remove hardcoded reference to localhost * fix: add error handling to the backend * docs: add information about E2B --------- Co-authored-by: Akhilesh Rangani <akhileshrangani4@gmail.com>

### Backend
|
||||
|
||||
The backend consists of a primary Express and Socket.io server, and 3 Cloudflare Workers microservices for the D1 database, R2 storage, and Workers AI. The D1 database also contains a [service binding](https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/) to the R2 storage worker.

The D1 database also contains a [service binding](https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/) to the R2 storage worker. Each open sandbox instantiates a secure Linux sandboxes on E2B, which is used for the terminal and live preview.

You will need to make an account on [E2B](https://e2b.dev/) to get an API key.
