…er entry access Restructure dict keys allocation to store dk_indices before the PyDictKeysObject header and keep dk_entries after the header. Update dict index access and related allocation/free/clone paths, adjust gdb dict entry location logic, and add layout coverage tests. Local dict microbenchmarks showed about a 1.4% overall improvement, with most operations around 1-2% faster.
