Head commit for run: 021f48f99464e95d4658ae5974f26c2faf267bd2 / Tanma <[email protected]> IRR: add bracketed Newton-Raphson fallback for divergent cases The unguarded Newton-Raphson iteration in Irr.irr() can converge to financially meaningless rates below -100%, or return NaN for cash flows that have an ordinary root (follow-up to bug 64137, which raised the iteration cap but left the divergence itself in place). Keep the historical loop as an unchanged fast path so existing results are identical, and only when it returns NaN or a rate <= -1 fall back to a bracketed Newton-Raphson with bisection safeguard over (-1, 10000]. The warn logs move to the fallback, where a NaN really is final.
