Add component or other identifier to logs

Currently we just have the timestamp, resulting in messages such as

```
2025-03-19T22:04:18.5801517Z /bin/sh: 1: source: not found
2025-03-19T22:04:18.5838246Z /bin/sh: 1: nvm: not found
2025-03-19T22:04:18.5839104Z /bin/sh: 1: nvm: not found
```

This is unhelpful for determining where the error may have occurred.
