Refactor generator completion checks for consistency.

Replaced `.is_complete()` method calls with direct `.complete` attribute access to streamline the code. Removed the redundant `is_complete()` method from `deepresearch.py` to reduce unnecessary indirection. This simplifies the logic and improves readability.
