Function validateAll

validateAll<T, E>(
results: readonly Result<T, E>[],
combineErrors: (left: E, right: E) => E,
): Result<T[], E>
Accumulate independent validation failures into a single combined error via combineErrors. Returns Ok<T[]> only when every input is Ok; otherwise returns Err<E> where E is the fold of all failures.

Unlike combine, this does not short-circuit on first failure — use for independent checks where you want to report all problems at once.
Type Parameters
- T
- E
Parameters
- results: readonly Result<T, E>[]
- combineErrors: (left: E, right: E) => E
Returns Result<T[], E>
Example
```
validateAll(
  [validateName(input), validateAge(input), validateEmail(input)],
  (left, right) => [...left, ...right],
);
// Result<string[], FieldError[]>
```
