Fix Ollama parsing error

[FindBoat]

It seems that langchain's with_structured_output sometimes fails to parse the structured AgentOutput response, but there's valid json output inside raw response. I'm not langchain expert, if there's a better way to deal with, I'm happy to fix.

Also renames examples/models/ollama.py to examples/models/ollama_example.py to avoid import conflict: ImportError: cannot import name 'ChatOllama' from partially initialized module 'langchain_ollama' (most likely due to a circular import)

I tried to generate new tests but there might be some issues in your codebase that I couldn't fix.

🐛 Bug Detection

Potential issues found in the following files:

• browser_use/agent/service.py

The error occurs because when the registry’s execute_action method is called for an action that requires a browser argument, the extra argument is not being forwarded to the action function. In our test, we explicitly pass browser=mock_browser, yet when the function (test_action_with_browser) is invoked, it is missing the required positional argument "browser". This indicates that the implementation in the registry’s execute_action method (in browser_use/controller/registry/service.py) is incorrectly handling (or omitting) the extra keyword arguments that should be passed to the action function.

🐛 Bug Detection

Potential issues found in the following files:

• browser_use/agent/service.py

The error is caused by a bug in the code being tested rather than a misconfiguration of the test or a problem with the test itself. In the Registry’s execute_action implementation (in browser_use/controller/registry/service.py), the extra arguments (in this case, the browser) are not being passed through correctly to the action function. The test “test_execute_action_with_and_without_browser_context” expects that when a browser is provided via extra arguments, the action function (test_action_with_browser) will receive it. Instead, the action is invoked without the required “browser” parameter, resulting in a TypeError.

In my opinion, this still don't resolve the iusse:

Trying the new implementation, the Response still contains an empty content: {'raw': AIMessage(content='', additional_kwargs={}, response_metadata={'model': 'llama3.2', 'created_at': '2025-02-15T11:18:59.924575Z', 'done': True, 'done_reason': 'stop', 'total_duration': 1298690250, 'load_duration': 73070250, 'prompt_eval_count': 2318, 'prompt_eval_duration': 475000000, 'eval_count': 27, 'eval_duration': 734000000, 'message': Message(role='assistant', content='', images=None, tool_calls=None)}, id='run-4f2677a4-a3f8-4a6f-9033-bbcc206a0549-0', tool_calls=[{'name': 'go_to_url', 'args': {'url': 'https://www.kayak.com/flights/'}, 'id': '1f56e00e-5521-4594-acbc-aa29b9906633', 'type': 'tool_call'}], usage_metadata={'input_tokens': 2318, 'output_tokens': 27, 'total_tokens': 2345}), 'parsing_error': KeyError('go_to_url'), 'parsed': None}
