Subject: [PATCH] feat: Implement optimized bubble sort algorithm

- Add bubble sort implementation with O(n) best case optimization
- Handle edge cases (empty and single-element lists)
- Ensure immutability by working on list copy
- Include optimizations for early termination and range reduction
- Add basic test suite for verification

Resolves: Implementation of bubble sort algorithm
