Mish Ushakov dc54fe0200 Parse chown on Docker COPY (#1071)
<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Adds support for parsing ownership on file copy operations in
Dockerfile-based templates.
> 
> - JS: Update `dockerfileParser.ts` to treat `COPY/ADD` as
`ModifiableInstruction`, parse `--chown` via `instruction.getFlags()`,
and pass `user` to `templateBuilder.copy(src, dest, { user })`
> - Python: Update `_handle_copy_instruction` in `dockerfile_parser.py`
to extract `--chown=<user[:group]>` and pass `user` to
`template_builder.copy(src, dest, user=user)`
> - Tests: Add JS and Python (sync/async) tests verifying `COPY --chown`
parsing and argument propagation
> - Changeset: Patch releases for `@e2b/python-sdk` and `e2b`
>

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

4. Check docs

Visit E2B documentation.

5. E2B cookbook
