• Fix write_obs / write_var row-count check under the
  nullable-string-array encoding – the shape guard read len() of the
  index element, which for the group encoding used by anndata >= 0.13 /
  pandas >= 3.0 counts the group's values / mask members (always 2)
  rather than the number of rows. This made valid writes raise
  ValueError: DataFrame has N rows but the file has 2 cells (or genes)
  and caused genuine shape mismatches to go undetected. The check now resolves
  the index element correctly for both flat-dataset and group encodings, and
  honours the _index attribute for renamed indices. standardise_gene_names
  with inplace=True is fixed as a consequence.
