fp

The fp worker moves bulk data worker→worker. fp::pipe runs a short pipeline in one call: each step triggers a function and its result lands in the next step's payload at into (default /value); the caller receives per-step sizes and a preview — never the value itself. The ten fp::* transforms mirror their lodash namesakes, take input at value, and run inline as pipe steps, threading the transformed value itself onward — their { value } response wrapper appears only on standalone direct calls (fine for small values).
