[Python SDK] Mixing threads and async code

[pocesar]

Describe the bug

The code contains a dangerous mix of threading.Lock, background threads, asyncio counterparts, requests blocking calls, dynamic lock creation and no timeout on most acquired locks.

Since most of the time you'll be using FastAPI + decorators for skill / reasoner, it'll always be a single event loop that can be blocked by blocking or nested calls.

It's very hard to debug when this happens, and some runs can stay stuck in time for hours. I recommend adding mypy and ruff for strict checks of async / blocking code

Steps to reproduce

1. Go to '...'
2. Run '...'
3. See error
