I've made further performance improvements that enhance not only the `assign` functions mentioned in this PR but also other operations such as copy/move constructors, insert, `{assign, append, insert}_range`, and `reserve` functions using bit manipulation techniques. Therefore, I closed this PR for now and will present the performance improvements in a more unified manner. I may need to split the improvements into smaller, self-contained PRs to ensure they are easier to review.
