`repeat` helper uses unparsed `rawNum` instead of `parseInt`-parsed `num` in loop condition

In `src/helpers/repeat.ts`, the `repeat` helper parses the user-provided count argument using `Number.parseInt(rawNum)` and stores the result in `num`. However, the subsequent `for` loop incorrectly uses the original `rawNum` (a string) in the comparison `i < rawNum` instead of the parsed integer `num`.

This works accidentally due to JavaScript's implicit type coercion in the `<` operator (string is coerced to number), but it is semantically incorrect and could lead to unexpected behavior with edge-case inputs (e.g., strings with trailing whitespace or non-numeric suffixes like `"5abc"` which `parseInt` parses as `5` but string comparison would behave differently).

**Affected file**: `src/helpers/repeat.ts`, line 12

```javascript
// Before (bug):
for (let i = 0; i < rawNum; i++) {

// After (fix):
for (let i = 0; i < num; i++) {
```
