⚡️ Speed up function sorter by 222,606%

The optimization replaces a manual bubble sort implementation with Python's built-in `arr.sort()` method, achieving a **222,606% speedup** by eliminating the O(n²) nested loops.

**Key Changes:**
- **Removed nested loops**: The original code used two nested `for` loops that resulted in O(n²) time complexity, executing millions of comparisons and swaps for larger arrays
- **Used built-in sort**: Python's `list.sort()` uses Timsort algorithm with O(n log n) average complexity and is implemented in highly optimized C code

**Why This Creates Massive Speedup:**
- **Algorithmic improvement**: O(n²) → O(n log n) means exponentially fewer operations as data size grows
- **Native implementation**: Built-in sort runs in C, avoiding Python interpreter overhead for each comparison/swap
- **Optimized for real-world data**: Timsort performs exceptionally well on partially sorted data and handles duplicates efficiently

**Performance by Test Case Type:**
- **Small arrays (≤10 elements)**: 25-93% faster due to reduced function call overhead
- **Large arrays (1000 elements)**: 8,945% to 104,669% faster, with the largest gains on reverse-sorted data where bubble sort performs worst
- **Edge cases**: Consistent 40-85% improvements even for special values (NaN, infinity, mixed types)

The optimization maintains identical behavior - same in-place sorting, same return value, same error handling - while dramatically reducing computational complexity.
