New rule: 'AI Wrote This' flair required for LLM-generated posts

Hi everyone. Just saw the new rule about the 'AI Wrote This' flair. I think it's a good idea for clarity.

I'm currently building my first pipeline (Airbyte → BigQuery → dbt) and sometimes use an LLM to help with Python snippets or SQL transformations. For example:

```python
# Asking for help with a date conversion in a PyAirbyte flow
def convert_epoch(epoch_int):
# LLM helped refine this try/except
try:
return datetime.fromtimestamp(epoch_int)
except ValueError:
return datetime.fromtimestamp(epoch_int / 1000)
```

If I post a question here later that includes code an AI helped write, should I use the flair? Even if I've tested and modified the output myself? Want to make sure I follow the rules correctly.
