…h GNU behavior Changed ResolveMode from Logical to Physical for -f, -e, and -m flags in readlink to ensure symlinks are followed before resolving '..' (parent directory), matching GNU readlink's physical resolution order for compatibility. Added a test case to verify the symlink resolution occurs before parent directory evaluation.
Add 'parentdir' to the ignored words to suppress spell-checker warnings, as it's used in test scenarios and not a misspelled term.
