Problem 2: Rebase rigid-shear and Cherry-Pick Override Commit

[SukiCai]

Summary

This PR is to complete Problem 2 for CHEM281 Homework 2.

Related Issue(s)

• rigid-shear branch rebased to develop branch
• add missing override commit has been cherry pick from maintenance to rigid-shear branch
  • Note: add missing override is an empty commit, git commit --allow-empty has been applied according to the instructions

The commit dcf2dd2 ("indexing bug fix for ghost comm of remapped velocities across PBC when group all is not used") was dropped because it already exists in the develop branch. During the rebase of rigid-shear onto develop, this commit appeared in the branch history as part of the common base, but it does not represent any unique changes introduced by the rigid-shear branch. Keeping it would duplicate a commit that’s already part of the upstream develop history. Therefore, it was safe and appropriate to drop it to ensure the rebased branch contains only the two required commits :)
