PR Summary

• Introduction of the unsq variable
  A new variable called unsq has been added. Its purpose is to simplify the operations related to unsquashing, which involves merging multiple changes into a single one for easier tracking and organization.

• New reference point for the 'master' branch
  The variable new-master has been added. This creates a new point of reference to the master branch which can be used to fetch the latest updates or changes made in the master branch more efficiently.

• New reference point for the 'main' branch
  Similarly, we've introduced the new-main variable that serves the same purpose as new-master but for the main branch. This addition is designed to make interacting with the main branch more straightforward and efficient.
