.SYNOPSIS
    Determines whether a given file or directory should be excluded.

.DESCRIPTION
    The Test-ShouldExclude function calculates the relative path of the given FileSystemInfo object
    from the source directory and splits it into parts. If any part of the path (i.e., a directory name)
    starts with a dot or matches an entry in $excludedDirs, the item is excluded.
    Additionally, for files, it checks if the filename is in the $excludedFiles list or 
    if the file matches any pattern in the .gitignore file.
