fix: use json.dumps instead of str() for Codex Responses API arguments

Browse source 
When the Responses API returns tool call arguments as a dict,
str(dict) produces Python repr with single quotes (e.g. {'key': 'val'})
which is invalid JSON. Downstream json.loads() fails silently and the
tool gets called with empty arguments, losing all parameters.

Affects both function_call and custom_tool_call item types in
_normalize_codex_response().
