colima start hangs, colima status returns error retrieving current runtime: empty value, Docker socket never created (macOS arm64)

### Description

On macOS arm64, `colima start` appears to start a VM but never reaches a usable Docker runtime.

Symptoms:
- `colima list` shows profile as `Running`
- `colima status` fails with:
- `error retrieving current runtime: empty value`
- Docker socket is never created at:
- `~/.colima/default/docker.sock`
- `docker --context colima ...` fails because socket is missing

I also see repeated daemon log lines:
- `waiting for VM to start` (every 5s)

And in VM serial logs, `cloud-final.service` fails, with cloud-init exiting non-zero during provisioning.

### Version

- Colima: `0.10.1`
- git commit: `ed905203afdbc6fd4eae6cc301918099ff31e86e`
- qemu-img: `11.0.0`
- Lima: `2.1.1`
- Host architecture: `arm64`
- macOS:
- `ProductVersion: 26.2`
- `BuildVersion: 25C56`

### Operating System

- [ ] macOS Intel <= 13 (Ventura)
- [ ] macOS Intel >= 14 (Sonoma)
- [ ] Apple Silicon <= 13 (Ventura)
- [x] Apple Silicon >= 14 (Sonoma)
- [ ] Linux

### Output of `colima status`

```
...
time="..." level=fatal msg="error retrieving current runtime: empty value"
```

### Reproduction Steps

1. Install/upgrade Colima and Lima with Homebrew:
```
brew install colima lima
# or
brew upgrade colima lima
```

2. Remove any existing Colima profile:
```
colima delete -f
```

3. Start Colima with Docker runtime:
```
colima start --runtime docker
```
(Issue is also reproducible with both `--vm-type vz` and `--vm-type qemu`.)

4. After startup completes (or appears to hang), run:
```
colima status
colima list
docker --context colima ps
ls ~/.colima/default/docker.sock
```

5. Observe:
- `colima status` returns: `error retrieving current runtime: empty value`
- `colima list` may still show profile as `Running`
- `~/.colima/default/docker.sock` is missing
- Docker commands against `colima` context fail
