⚡️ Speed up function mysorter by 35,154%

The optimization replaces the manual O(n²) bubble sort implementation with Python's built-in `arr.sort()` method, which uses Timsort - a highly optimized hybrid stable sorting algorithm with O(n log n) complexity.

**Key changes:**
- Eliminated nested loops that performed ~14 million iterations for large inputs
- Replaced manual element swapping with optimized C-level sorting
- Reduced algorithm complexity from O(n²) to O(n log n)

**Why this leads to dramatic speedup:**
The original bubble sort has quadratic time complexity, making ~n²/2 comparisons and up to n²/2 swaps. For a 1000-element array, this means ~500,000 operations. Python's Timsort leverages existing order in data and uses optimized merge strategies, requiring only ~10,000 operations for the same input.

**Performance characteristics by test case:**
- **Small lists (≤10 elements)**: 20-75% faster due to reduced overhead
- **Large sorted/reverse-sorted lists**: 60,000-100,000% faster as Timsort detects existing runs
- **Large random lists**: 45,000-52,000% faster from algorithmic improvement
- **Lists with duplicates**: Excellent performance as Timsort handles equal elements efficiently

The line profiler shows the original code spent 95% of time in comparison and swapping operations, while the optimized version completes all sorting in a single optimized call.
