Status pill for state words (ahead / behind / steeping / blocked); sans text on a muted tint.

```jsx
<Badge tone="ok" dot>ahead</Badge>
<Badge tone="warn" dot>drifting</Badge>
<Badge tone="danger">blocked</Badge>
```

Tones: ok, warn, danger, info, neutral, jade (jade = agent/forecast flavor). Use `Tag` instead for verbatim gitea labels like `est/3d`.
