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
Just a small fix of some broken hyperlinks in the documentation of the
function `langchain_openai/chat_models/base.py#with_structured_output`
and a rephrase of the reference to supported models.

```
If the `stdout` "done marker" arrives before the `stderr` output is
enqueued, the method returns early without capturing the `stderr` line.
The two reader threads run independently with no synchronization
guaranteeing `stderr` arrives before the done marker.
In environments with Python 3.10, timing differences can cause the
`stdout` marker to win the race, resulting in `<no output>` instead of
`[stderr]` error.
Observed as a flaky test on `test_stderr_output_labeling` in CI:
```shell
FAILED tests/unit_tests/agents/middleware/implementations/test_shell_tool.py::test_stderr_output_labeling - AssertionError: assert '[stderr] error' in '<no output>'
```
