[Bug]: start failed NSPOSIXErrorDomain Operation not permitted

### I have done the following

- [x] I have searched the existing issues
- [x] If possible, I've reproduced the issue using the 'main' branch of this project

### Steps to reproduce

I am unable to run any container on my system

container system start
container create --name alpine alpine
container start alpine

container system logs -f

### Current behavior

Unable to start any container

### Expected behavior

Should be able to run a container

### Environment

```markdown
- OS: 26.0.1
- Xcode: N/A
- Container: version 0.5.0 (build: release, commit: 48230f3)
```

### Relevant log output

```shell
2025-10-04 18:18:13.757551-0700 0x142a05 Info 0x0 36144 0 container-runtime-linux: [com.apple.container:RuntimeLinuxHelper] starting start [uuid=alpine]
2025-10-04 18:18:13.763546-0700 0x142a05 Error 0x0 36144 0 container-runtime-linux: [com.apple.container:RuntimeLinuxHelper] start failed [uuid=alpine] [error=Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"]
```

### Code of Conduct

- [x] I agree to follow this project's Code of Conduct

Start by running the reported `container system start`, `container create --name alpine alpine`, and `container start alpine` commands on the stated environment, then inspect `container system logs -f` for the `RuntimeLinuxHelper` permission failure. Done means an Alpine container starts successfully without the `NSPOSIXErrorDomain` Operation not permitted error.
