Sixth layer of the unification. PipelineEngine.run() accepts start_at= (string node id or callable reference) to begin execution mid-DAG. Nodes not reachable from start_at are treated as pre-completed and skipped. Resume (run_id) and approve_pause already landed in layers 1A and 5; this completes the entry-control kwargs. Engine changes: - run() accepts start_at: str | Callable | None = None. - New _resolve_node_id helper at module level. - pre_completed initialized from all_nodes - forward(start_at). - Works with state overlay, edge conditions, and cyclic mode. Tests: 7 new in tests/unit/pipeline/test_pipeline_engine_start_at.py. Full suite: 1594 passed. Refs: #245

Sixth layer of the unification (#245).
PipelineEngine.run()acceptsstart_at=(string node id or callable reference) to begin execution mid-DAG. Nodes not reachable fromstart_atare treated as pre-completed and skipped — the unified equivalent ofStatePipeline.invoke(state=..., start_at=...).resume(run_id=...) and approve_pause already landed in layers 1A (#246) and 5 (#251); this layer completes the trio of entry-control kwargs.
