Summary

Successfully added Python client thread/multi-processing safety notes to the documentation as requested by @rubenfiszel.

Changes made:

• Workflow as Code (docs/core_concepts/31_workflows_as_code/index.mdx): Added a note after the multiprocessing example explaining that users should create separate client instances per thread/process using wmill.Windmill() as the client is not thread-safe
• Python Client (docs/advanced/2_clients/python_client.md): Added a prominent note at the beginning of the documentation warning users about thread safety limitations

Both notes follow the repository's writing guidelines: concise, technical language without marketing fluff.
