📝 Walkthrough

Walkthrough

This PR makes targeted refinements to MultiVersionControl.java affecting both directory-discovery logic and status-message output. The addCheckoutCvs method replaces its parent-traversal while loop with a for loop structure, and removeCommonSuffixDirs caches a parent-directory computation to improve its suffix-stripping loop. For Git and Mercurial status commands, the code updates message templates to reference the local dir variable directly rather than accessing the ProcessBuilder's directory through pb.directory().
