## Why
The skill toggle view truncated every display name to 21 characters, even when
the popup had enough room to show more. This could hide the part that
distinguishes similarly named skills.
## What changed
- Pass full skill display names to the shared row renderer so it can fit them
to the available width alongside descriptions.
- Keep narrow layouts bounded by the renderer's width-aware truncation.
## Testing
Added coverage for preserving and filtering full display names, plus snapshots
for wide and narrow popup layouts.
