Add opt-in crash-consistent streaming resume for compatible local CSV/JSONL operators, with durable progress tracking, recovery, and regression tests. Default streaming behavior remains unchanged.

Summary
Streaming pipelines may duplicate records when interrupted after writing output but before saving progress.
This PR adds an optional safer resume mode for compatible local CSV/JSONL pipelines.
Changes
Testing
This mode requires compatible operators and a single local writer. External side effects and power-loss durability are not covered.
