Test ToolSearch logging with MCP-heavy environment

[djdarcy]

Summary

The ToolSearch tool (tool_search_tool_regex, tool_search_tool_bm25) logging support was added but needs real-world testing.

Background

ToolSearch triggers automatically when MCP tools would consume >10% of context. It's not manually invocable.

Testing Requirements

• Set up environment with 10+ MCP servers or many MCP tools
• Verify ToolSearch triggers and logs correctly
• Confirm format: {tool_search_tool_regex: <query> }

Current Implementation

elif tool_info.name in ("tool_search_tool_regex", "tool_search_tool_bm25"):
    return tool_input.get("query", "")

Added to TOOL_CATEGORIES under "search" category.
