style: minor feed item style tweaks

This commit applies minor style-related adjustments to the FeedItem Svelte component.

- Wraps robot icon markup for clearer containment.
- Adjusts conditionals and header logic for more explicit structure and simpler styling.

No functional behavior is changed, this commit introduces only presentational changes to the component markup.
