Pass the purge confirmation under the key expected by the CLI.

cli.mjs reads the purge confirmation from purgeConfirm. The workflow supplies confirm, so PromptController does not find an answer and throws in non-interactive mode.

Suggested fix 
-            --answers '{"confirm":"DELETE"}'
+            --answers '{"purgeConfirm":"DELETE"}'

Update the uninstall command’s --answers value to use the purgeConfirm key
expected by the CLI, so PromptController receives the purge confirmation in
non-interactive mode.

To use Podman, run `install --engine podman` or select it in the interactive installer.

## Container engines: Docker and Rootless Podman

SpaceApp supports Docker and rootless Podman as container engines:

- **Docker** (default): Docker Engine or Docker Desktop on Linux, macOS, and Windows.
- **Rootless Podman**: Podman 5+ with Compose support (`podman compose version`) on Linux and macOS.

To install using Podman:

```bash
npx --yes run-spaceapp@latest install --engine podman
```

On Linux and macOS, if Docker is unavailable but Podman is detected on PATH, the interactive installation wizard automatically offers to use Podman.

### Podman considerations

- **Rootless by default**: Podman executes under your user account with user namespace mapping (`keep-id:uid=10001,gid=10001` for unprivileged containers).
- **SELinux compatibility**: Registered workspace bind mounts are automatically annotated with `:z` relabeling for SELinux enforcing environments.
- **cgroup v2 & Resource limits**: On Linux, cgroup v2 with CPU and memory delegation (`Delegate=cpu cpuset io memory pids` in systemd) enables resource limit enforcement. If controller delegation is not configured, containers run without CPU/memory limits.
- **macOS virtual machine resources**: Ensure your Podman machine has sufficient CPU, RAM, and disk for your selected profile (e.g. `podman machine set --cpus 4 --memory 11264 --disk-size 50`).
- **Access mode limitation**: The `--access host-root` mode requires Docker daemon host mount semantics and is not supported with rootless Podman. Use `--access isolated` (the default).
- **Engine switching**: Switching the container engine on an existing installation is not directly supported. To migrate between Docker and Podman, create a backup with `run-spaceapp backup`, reinstall with `--engine <engine>`, and restore with `run-spaceapp restore`.

## Installation profiles

## Container Engines: Docker and Rootless Podman

SpaceApp supports both Docker and rootless Podman as container engines:

- **Docker** (default): Docker Engine or Docker Desktop on Linux, macOS, and Windows.
- **Rootless Podman**: Podman 5 or newer with Compose support (`podman compose version`) on Linux and macOS.

To install with Podman:

```bash
npx --yes run-spaceapp@latest install --engine podman
```

Or select Podman interactively during installation. If Docker is not found on Linux or macOS but Podman is available, the launcher automatically prompts to use Podman.

### Podman Requirements and Characteristics

- **Rootless execution**: Podman runs rootless under your user account with user namespace mapping (`keep-id:uid=10001,gid=10001` for unprivileged containers).
- **SELinux compatibility**: Host workspace bind mounts automatically receive `:z` relabeling so containers can access registered workspaces under SELinux enforcing mode.
- **cgroup v2 & Resource limits**: On Linux, cgroup v2 with CPU and memory controller delegation (`Delegate=cpu cpuset io memory pids`) is recommended for enforcing resource limits. If systemd controller delegation is not configured, containers run without CPU/memory limits.
- **macOS Podman Machine**: On macOS, Podman runs inside a virtual machine. Ensure the machine has adequate resources for your profile (e.g. `podman machine set --cpus 4 --memory 11264 --disk-size 50`).
- **Access mode limitation**: The `--access host-root` mode requires Docker daemon host mount semantics and is not supported with rootless Podman. Use `--access isolated` (the default) with Podman.
- **Engine switching**: Switching the container engine of an existing installation is not supported directly. To switch between Docker and Podman, back up your installation with `run-spaceapp backup`, reinstall with `--engine <engine>`, and restore with `run-spaceapp restore`.
