THEN Modify the `apply_writes` function (e.g., in `langgraph/pregel/algo.py`) to treat END channel writes as a special case that does not require explicit channel registration, skipping the warning for 'branch:to:__end__' channels. This preserves functionality while eliminating the cosmetic warning.

```python
# In apply_writes, add a check:
if channel_name == f"branch:to:__end__":
    continue  # Skip warning for END channel writes
```
