Extract _convert_and_split() helper in both test files to eliminate
duplicated filtering logic across tests. Add test for tool_call
without id being silently skipped (crewai tc_id is None guard).

Apply the same parentMessageId orphan fix to crewai_flow_messages_to_copilotkit
where the elif chain meant tool-call messages never emitted the parent assistant
message. Also refine langgraph fix: use explicit None check instead of truthiness,
add inline comments explaining the invariant, remove unused pytest import,
replace fragile commit hash in docstring, and add test for list-type content.

Verifies that langchain_messages_to_copilotkit always emits the
assistant message even when content is empty (OpenAI-style tool-call-only
responses), ensuring no orphaned parentMessageId references.
