(frontend) Allow word break in conversation title Crop

[eliott07]

Feature Request

Improve how conversation titles are visually truncated in the sidebar so that they make better use of the available horizontal space while remaining constrained to a single line.

Today, titles are shortened in between words with an ellipsis when they exceed the available width. In some cases, this results in large unused gaps at the end of the line, causing multiple distinct conversations to appear identical or overly similar at a glance. This is particularly noticeable for long, technical, or structured titles.

The requested improvement aims to increase information density and scannability of conversation titles in the left panel, without changing the underlying data or allowing multi-line titles.

Expected Outcome

• Sidebar titles remain limited to one line
• More characters are visible before truncation
• Users can more easily differentiate between conversations with similar prefixes
• No impact on stored conversation titles or backend behavior
