Add nthroot and isqrt numeric-analysis functions

nthroot(x, n): general n-th root, x^(1/n). Requires n to be a non-zero
whole number; negative x is only valid for odd n, matching cbrt's
existing convention (cbrt(-8) == -2).

isqrt(n): integer square root, the largest integer m with m*m <= n.
Computed via f64::sqrt with an explicit correction step to guard
against floating-point rounding pushing the initial estimate off by
one in either direction.

Function count 212 -> 214.
