QA: Tool name displayed twice in Live Block summary

[randomm]

Bug

Tool lines show the tool name twice:

✓ bash bash remory search "architecture stack components"
✓ read read ratcher/README.md
✓ check_task check_task tsk_c00d947a3001...

The cyan tool name is rendered by liveblock.ts, but the summary string from index.ts also prepends the tool name.

Root Cause

In index.ts streamResponse(), the summary is built as:

const summary = arg ? \`\${tool} \${arg}\` : tool

But liveblock.ts render() already outputs: icon toolName summary

So the tool name appears in both toolName AND summary.

Fix

Change the summary to just be the arg, not tool + arg:

const summary = arg || tool

Or simply pass arg as the summary and let the live block handle the tool name display.

Screenshots

Found during QA of commit 85c396e on feature/oclite-ui-components.
