Remove the stale binary and object files from the repository root directory
that are no longer referenced by the build system. Additionally, update the
atoms_get_window_name function to use AnyPropertyType instead of specific
atom types for XGetWindowProperty calls, and add a nil check on nitems to
prevent potential null pointer dereferences. Modify panel_handle_click to
minimize the currently focused client when clicking on it, rather than
keeping it focused, improving window management behavior.
