Inconsistent emoji width

Emoji width is either 1 or 2, and this is inconsistent across terminals.

Something like this should fix:
```typescript
process.stdout.write('🪲');
process.stdout.cursorTo(2);
process.stdout.write(`Log saved to: ${stage.logger.outFile}\n`);
```

But it doesn't work in the tests because `process.stdout` is not accessible.
