* fix(github_copilot): preserve encrypted_content in reasoning items for multi-turn conversations
GitHub Copilot uses encrypted_content in reasoning items to maintain conversation
state across turns. The parent class (OpenAIResponsesAPIConfig._handle_reasoning_item)
strips this field when converting to OpenAI's ResponseReasoningItem model, causing
"encrypted content could not be verified" errors on multi-turn requests.
This override preserves encrypted_content while still filtering out status=None
which OpenAI's API rejects.
