## list

List all registered runners with live status.

```bash
grm list
```

This command takes no arguments or options. It displays a table with columns: NAME, HOST, USER, LABELS, STATUS for all runners stored in the local registry at `~/.local/share/grm/runners.json`.

The status is checked live by running an Ansible ad-hoc command on each remote host (`systemctl --user is-active gitea-runner`). Possible status values: `active`, `inactive`, `failed`, `unknown`.

**Example output:**

```
NAME              HOST            USER       LABELS                         STATUS
------------------------------------------------------------------------------------------
prod-runner       192.168.1.10    ubuntu     docker:docker://gitea/...      active
build-runner      192.168.1.10    ubuntu     docker:docker://gitea/...      active
test-runner       192.168.1.20    ubuntu                                    inactive
```

If no runners are registered:

```
No runners registered. Use 'grm install' to add one.
```

## --version

Show the installed GRM version.

```bash
grm --version
```

This reports the version from `__version__` in `src/gitea_runner_manager/__init__.py`, which is the single source of truth set by the automated release pipeline.

## Environment Variables

All CLI options can be set via environment variables (loaded from `.env` via python-dotenv). Command-line flags take precedence over environment variables.
