refactor: standardize explorer action wrapping and fix module requires

- Use wrap_explorer for change_root_to_parent to match other API methods
- Fix incorrect require paths in dir-up.lua (remove "lua." prefix)
- Remove unused explorer variable in change-dir.lua
- Move change_dir assignment in Explorer:new before _load call
- Add find_file require to explorer/init.lua for dir_up method
