Mish Ushakov 4e16cffc2f feat(js-sdk): add proxy connection param (#1386)
Adds a `proxy` connection parameter to the JS SDK, mirroring the Python
SDK. When set, requests are routed through the given HTTP proxy via an
undici `ProxyAgent` dispatcher (fetchers are cached per-proxy so
non-proxy traffic is unaffected). It applies to control-plane API
requests, all requests made to the returned sandbox (REST plus
filesystem/commands/pty RPC), and volume requests. Behavior is unchanged
when no proxy is provided, and unit tests cover both the API and envd
fetch paths.

## Usage

```ts
import { Sandbox } from 'e2b'

// Routes API + all sandbox requests through the proxy
const sandbox = await Sandbox.create({
  proxy: 'http://user:pass@127.0.0.1:8080',
})
await sandbox.files.write('/hello.txt', 'world')

// Also works when connecting to an existing sandbox
const sbx = await Sandbox.connect(sandboxId, { proxy: 'http://127.0.0.1:8080' })
```

> Proxying relies on the optional `undici` package and the Node runtime;
in browser/edge runtimes requests use global `fetch`, which has no proxy
support (same as the existing HTTP/2 dispatcher).

patch patch

Fix proxy not being applied to volume content requests. Volume.create/Volume.connect now store the proxy on the returned instance, so instance methods (list, readFile, writeFile, makeDir, getInfo, updateMetadata, remove, …) route through it without having to pass proxy on every call. A per-call proxy still takes precedence.
