⚡️ Speed up function sorter by 73%

Here is an optimized version of your `sorter` function.  
**Key changes:**  
- Your version is a naive **bubble sort**, which is very inefficient for even moderately sized arrays.
- The fastest in-place sort for general Python lists is **Timsort**, accessible as `arr.sort()`. This is highly optimized in C and significantly faster than any explicit sorting loop in Python.
- All major per-line costs (swapping, comparison, outer/inner loops) drop to near-zero by using the built-in `sort`.

**The function signature and return type remain unchanged. Comment preservation per your instructions.**




This will be orders of magnitude faster (from O(n^2) to O(n log n) with C-level performance).

---

**If you're required to keep a manual in-place sort for didactic reasons** (less likely, but just in case), use an optimized **bubble sort**:  
- Avoid redundant passes if the array is already sorted (early exit).
- Reduce the sweep with each successive pass (because the end of the list is already sorted).

Here is a fast manual bubble sort version.



**But for maximal speed:** use the built-in sort.  
The first code block is best for your needs.
