Ruff cleanup

[evelynmitchell]

I've cleaned up all the ruff errors I could, by removing a few duplicate imports, and silencing the errors which were incompatible with what your code intended.

There are two ruff errors left I don't know how to fix:

$ ruff check
swarms/tools/py_func_to_openai_func_str.py:22:51: F811 Redefinition of unused `get_args` from line 17
tests/agents/test_agent_logging.py:7:1: F811 Redefinition of unused `parse_and_execute_json` from line 4
Found 2 errors.

Thanks for looking at this.
