fix: Correct ToolCall object structure for Gemini text parser

- Use tool_call.name instead of tool_call.function.name
- Use tool_call.args (dict) instead of tool_call.function.arguments (JSON string)
- Match expected structure at line 1543
- Fixes: AttributeError 'ToolCall' object has no attribute 'name'
