Function cmp_numeric_to 

pub fn cmp_numeric_to<T: Numeric + Copy + 'static>(
    lhs: &[T],
    rhs: &[T],
    mask: Option<&Bitmask>,
    op: ComparisonOperator,
    output: &mut Bitmask,
) -> Result<(), KernelError>

Zero-allocation variant: writes directly to caller’s output buffer.

Unified numeric comparison dispatch with optional null mask support. The output Bitmask must have capacity >= lhs.len().
