fix(rebase): remove duplicate definitions and update stale module paths

Rebase left duplicate function blocks in worker.py (triple human_message
write causing 3x user messages in /history), deps.py, and prompt.py.
Also update checkpointer imports from the old deerflow.agents.checkpointer
path to deerflow.runtime.checkpointer, and clean up orphaned feedback
props in the frontend message components.
