Illegal instruction when using duckdb in docker sandboxes

### What happens?

When trying to use the `duckdb` python client inside a [docker sandbox](https://docs.docker.com/ai/sandboxes/), I'm encountering an `Illegal instruction` error:

```
>>> import duckdb
Illegal instruction
```

As I understand, the docker sandbox is basically a microVM. The host OS is macOS.

### To Reproduce

Follow [docker sandbox instructions](https://docs.docker.com/ai/sandboxes/get-started/) to create a sandbox, and open a shell inside it:

```
docker sandbox exec -it codex-jzn bash
```

(`codex-jzn` is simply the sandbox name)

Inside the sandbox, create a virtual env and install duckdb:

```
agent@codex-jzn:~$ uv venv && source .venv/bin/activate
Using CPython 3.12.12
(agent) agent@codex-jzn:~$ uv pip install duckdb
Resolved 1 package in 486ms
Prepared 1 package in 527ms
Installed 1 package in 227ms
+ duckdb==1.5.1
```

Then, trying to import `duckdb` will fail:

```
(agent) agent@codex-jzn:~$ python
Python 3.12.12 (main, Jan 14 2026, 19:35:10) [Clang 21.1.4 ] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import duckdb
Illegal instruction
```

Note: I also tried different versions of `duckdb`, same issue.
