[BUG] WebSearch tool results not visible in transcript (Ctrl+O)

What's Wrong?

WebSearch tool results are hidden from users. Unlike other tools (Bash, etc.), WebSearch doesn't show what it returned to Claude - even in transcript view (Ctrl+O).

Can't see which URLs, titles, or snippets were fed to Claude, making it impossible to verify sources or understand reasoning.

What Should Happen?

WebSearch results should appear in Ctrl+O transcript like other tool outputs, showing:

• Query used (already there)
• URLs returned
• Titles/snippets

Steps to Reproduce
