コントラクト
- assert set_key, unset_key, and rewrite expose follow_symlinks parameter defaulting to False
- assert set_key on symlink replaces link with regular file and leaves target untouched when follow_symlinks=False
- assert set_key on symlink mutates target and preserves symlink when follow_symlinks=True
- assert unset_key on symlink obeys follow_symlinks flag to avoid unintended target file modification
