v0.13.0

This release features **3 weeks of work** from **3 contributors**. It's focused on [unregistry](https://github.com/psviderski/unregistry) integration and expanding Compose support.

## Highlights

### Unregistry integration (push images to cluster)

We've integrated [unregistry](https://github.com/psviderski/unregistry) to make image distribution way easier. You can build your Docker images locally or on CI and push them directly to your Uncloud cluster without needing an external registry. Only the missing layers are transferred, making it efficient and fast.
```shell
# Push local Docker image to a specific or multiple machines.
uc image push IMAGE [-m/--machine NAME[,NAME]]

# Push local Docker image to all machines.
uc image push IMAGE -m all
```

See [`uc image push` documentation](http://uncloud.run/docs/cli-reference/uc_image_push) for more details and examples.

Under the hood, `uncloudd` daemon on each machine runs an embedded unregistry server that handles the image receiving and storage in `containerd`. `uc image push` requires [`containerd image store`](https://docs.docker.com/engine/storage/containerd/) to be enabled for Docker on the target machines.

This brings us one step closer to an end-to-end `uc deploy` experience which will handle building, pushing, and deploying images in one go.

### Inspect images

You can now inspect what images you have on your machines in the cluster.

```shell
# List all images on all machines.
uc images

# List images on specific machines.
uc images -m machine1,machine2

# List images filtered by name pattern.
uc images "myapp:1.*"
```

See [`uc images` documentation](http://uncloud.run/docs/cli-reference/uc_images) for more details and examples.

### Compose configs

PR: [#116](https://github.com/psviderski/uncloud/pull/116) Thank you @tonyo for the contribution! ❤️

Uncloud now supports [Compose configs](https://github.com/compose-spec/compose-spec/blob/main/08-configs.md) for managing configuration files in your services. Configs allow you to store non-sensitive configuration data separately from your container images and mount them into containers at runtime.

Example `compose.yaml` using configs:

```yaml
services:
  app:
    image: myapp:latest
    configs:
      - source: app_config
        target: /app/config.yaml

configs:
  app_config:
    # Local path is relative to compose.yaml location
    file: ./config.yaml
```

See [Configs documentation](http://uncloud.run/docs/concepts/compose/configs) for more details.

### Internal DNS improvements

PR: [#123](https://github.com/psviderski/uncloud/pull/123) Thank you @jabr for the contribution! ❤️

New machine-scoped DNS entries `<machine-id>.m.<service-name>.internal` allow targeting services on specific machines.
This is useful for debugging, health checks, or machine-specific routing needs.

See [Internal DNS documentation](http://uncloud.run/docs/concepts/services/internal-dns) for more details.

### Containerd image store integration

Uncloud now automatically configures Docker to use the [containerd image store](https://docs.docker.com/engine/storage/containerd/) by default on new machines, enabling:
- `uc image push` feature to push images directly to the cluster machines via [unregistry](https://github.com/psviderski/unregistry)
- ability to push and store multi-platform images

The system gracefully handles machines without containerd support and provides clear error messages when required features aren't available.

## Improvements

- `uc ls` now displays the `IMAGE` column showing which container image(s) each service is running
- Service containers now receive `UNCLOUD_MACHINE_ID` environment variable with the machine ID they are running on
- Updated Docker and Compose Go dependencies to latest versions for better compatibility

## Bug fixes

- Fixed panic in Docker when pushing images without authentication
- Fixed error handling when removing non-existent services
