docs: fix JSDoc tags in number/float16/base native variants

[Planeshifter]

Resolves none.

Description

Two small JSDoc corrections to native variants in number/float16/base, identified by comparing each lib/native.js against its siblings within the namespace. Both deviations match a 6-of-7 (86%) majority pattern across the C-addon subset.

number/float16/base/from-word

Adds the missing @private JSDoc tag to the wrapped function in lib/native.js. Six of seven (86%) sibling lib/native.js files mark the wrapped function @private — exponent, signbit, significand, to-float32, to-float64, to-word. from-word was the lone outlier.

number/float16/base/signbit

Removes a stray leading hyphen from the @returns tag in lib/native.js. The corrected form (@returns {boolean} boolean indicating if sign bit is on or off) matches the package's own lib/main.js and 6 of 7 (86%) sibling lib/native.js files. The leading-hyphen prefix is reserved for @param tags by stdlib JSDoc convention.

Disclosure
