Refactor benchmark to use randomized vectors instead of sets

- Replaced std::set with std::vector for sequence handling.
- Added randomization of sequences to avoid ordered input bias.
- Removed unused balance function and related code in bst.cpp and bst.h.
- Fixed bugs in list insertion and search logic.
- Updated plot.py to allow custom y-axis labels and enable log scale for build plots.
