🐞 Search Results Limited to Single Line Previews

### Description

Currently, search results only preview a single line, which often doesn't provide enough context.

### To Reproduce

1. Navigate to the search tab.
2. Enter a search term that is quite long.

### Expected Behavior

### Version Information

CodeEdit: 0.1.0
macOS: 14.4.1
Xcode: 15.3

### Additional Context

_No response_

### Screenshots

_No response_

Start in the search tab and reproduce the issue with a long search term on the reported CodeEdit version. Compare the current single-line preview with the expected screenshot; done means search results provide the additional context shown there without losing the existing search behavior.
