Fix: Handle filenames with spaces in mob next

Git's porcelain output quotes filenames containing spaces. The
getPathOfLastModifiedFile function was passing these quoted filenames
directly to os.Stat, causing failures on mob next.

- Unquote git-quoted filenames before calling os.Stat.
- Handle unquoting errors gracefully with warning messages.
- Bump version to 5.4.1.
