fix(claude): resolve empty tool name in Claude API requests

Browse source 
The ToolCall struct stores the tool name in Function.Name (OpenAI format)
but the Claude provider was reading tc.Name (top-level), which is always
empty. This caused 400 Bad Request errors on any conversation involving
tool calls.

Also handles the case where Arguments are stored as a JSON string in
Function.Arguments rather than the top-level map.
