Pull request overview

This PR fixes a bug in the tool evaluators that was preventing them from correctly handling built-in tool definitions provided by Agent v2. The fix removes an overly restrictive type check when validating that tool calls have corresponding tool definitions.

Key Changes

• Simplified tool definition lookup in _extract_needed_tool_definitions method by removing the type restriction
• Allows matching tool definitions by name alone, regardless of their type field value
