Mason Daugherty 516d74b6df fix(core): use get_type_hints for Python 3.14 TypedDict compatibility (#34390 )

Replace direct `__annotations__` access with `get_type_hints()` in
`_convert_any_typed_dicts_to_pydantic` to handle [PEP
649](https://peps.python.org/pep-0649/) deferred annotations in Python
3.14:

> [`Changed in version 3.14: Annotations are now lazily evaluated by
default`](https://docs.python.org/3/reference/compound_stmts.html#annotations)

Before:

```python
class MyTool(TypedDict):
    name: str

MyTool.__annotations__  # {'name': 'str'} - string, not type
issubclass('str', ...)  # TypeError: arg 1 must be a class
```

After:

```python
get_type_hints(MyTool)  # {'name': <class 'str'>} - actual type
```

Fixes #34291
