Jakub Novák 5a673d15c8 chore: distinguish between Sandbox and file not found (#1231)
<!-- CURSOR_SUMMARY -->
> [!NOTE]
> **Medium Risk**
> Changes public error/exception types in both JS and Python SDKs by
introducing new subclasses and remapping 404/NotFound conditions, which
may affect downstream error handling despite deprecation shims.
> 
> **Overview**
> **Distinguishes “sandbox not found” from “file/directory not found”
across the SDKs.** Adds `FileNotFound*` and `SandboxNotFound*`
error/exception types (with `NotFound*` marked deprecated) and updates
sandbox lifecycle APIs to throw `SandboxNotFound*` for
missing/non-running sandboxes.
> 
> Refactors envd HTTP/RPC error handling in both JS and Python to
support overridable status/code→error maps, and wires filesystem
operations to map 404/`NotFound` into `FileNotFound*`. Tests are updated
accordingly, and patch changesets are added for both packages.

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/code-interpreter

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. Execute code with code interpreter inside Sandbox

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

const sbx = await Sandbox.create()
await sbx.runCode('x = 1')

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