Summary

Add collapsible summary mode for tool executions in webchat UI to reduce visual noise

Problem to solve

Currently the webchat UI displays each tool execution as separate messages (e.g., "1 tool exec", "tool output"), creating excessive visual noise. When an agent runs multiple tools in one turn, users see dozens of individual messages that clutter the conversation and make it hard to follow the flow.

Proposed solution

Add a collapsible summary mode for tool executions:

1. Default: Show a single summary button like "📦 5 tool calls" instead of individual messages
2. Expand on demand: User clicks to expand and see individual tool details
3. Configurable: Add setting to choose between "detailed" and "summary" modes

Example:

• Current: "1 tool exec" → "tool output" → "2 tool exec" → "tool output"...
• Proposed: "📦 2 tool calls [expand]"
