Finance.CashFlow's moduledoc described the default solver as "Newton-Raphson with a bisection fallback." That was the old 1.0 solver; since 1.4.3 the default is a safeguarded Newton-Raphson (rtsafe), which interleaves a bisection step per iteration rather than falling back to bisection after Newton gives up. Reworded, and named the derivative-free Finance.Solver.Brent alternative.

Doc-only.

The default is a safeguarded Newton-Raphson (rtsafe), not "Newton-Raphson
with a bisection fallback" — bisection is interleaved per step, not a
separate fallback. Name the Brent alternative.
