"""Pipeline node factories. Each ``make_*_node`` returns a callable that
takes `PipelineState` and returns a partial state dict for LangGraph to merge.

Why factories: the graph topology is fixed but providers/index/registry are
runtime-injected. Keeping construction explicit (factory closures over deps)
makes tests trivial — pass fakes, run the node, assert the partial dict.
