Guard against empty type args when using bare dict or list annotations (no type parameters, e.g. instead of ). Previously: - construct_type() raised ValueError on bare dict - construct_type() raised IndexError on bare list - _transform_recursive() raised IndexError on bare dict Now these cases gracefully return the data as-is, matching the behavior of parameterized types when the data already matches. Fixes openai#3338, openai#3341

Problem
Using bare or annotations (without type parameters) crashes the SDK:
This affects users who annotate fields as plain or instead of or .
Fixes #3338
Fixes #3341
Root Cause
The code unconditionally unpacks type args without checking if they exist:
Fix
Guard the type args access:
Testing
Added 6 new tests covering bare dict/list in both and (sync + async). All 120 tests pass (114 existing + 6 new).
