Prevent blank tool calls when output is multi-line (vibe-kanban) (#1077)

* Done! The Oracle tool will now display "Oracle" next to its icon instead of rendering blank. All tool calls now consistently show: icon + tool name + optional inline summary.

* Done! Removed the colon separator to fix the i18n CI error. The Oracle tool will now display cleanly as "Oracle [summary]" with the existing gap spacing providing visual separation.

* Done! Now it shows either the inline summary (if available) or the tool name, not both. Oracle will display "Oracle" when there's no summary.
