Plugin list descriptions truncated regardless of terminal width

Description

When using the /plugin command to view installed plugins, the description text for each plugin is truncated even when the terminal is wide enough to display the full text.

Expected behavior

Plugin descriptions should respect the terminal width and display the full text when there is sufficient horizontal space available.

Current behavior

Descriptions are truncated with no way to see the full text inline, regardless of terminal width.

Environment

• Claude Code CLI
• Wide terminal (well beyond default 80 columns)

Suggestion

Make the plugin list UI terminal-width-aware so descriptions use the available horizontal space rather than truncating at a fixed column width.
