honor XDG_CONFIG_HOME for the config path

open #0005 issues/0005-honor-xdg-config-home-for-the-config-path.md opened
enhancement

getConfigPath builds the path by hand as $HOME/.config/dew/config.json, ignoring XDG_CONFIG_HOME.

grrs was explicitly moved onto XDG conventions ("refactor: separate file locations"), so dew should match. os.UserConfigDir() respects XDG on Linux and has a sane fallback elsewhere.
