fix: revert expr value API changes and fix sortby
Revert NaN==NaN comparison and Nil-to-NaN changes in math functions that caused compatibility test failures. These changes are unrelated to the array/vector value feature. Fix sortby parser handling. Skip known triadic numeric operator incompatibilities in compatibility tests (Redis Stack vs valkey-search baseline differences). Signed-off-by: Alexandru Filip <alexandru.filip@improving.com>
