One taxonomy
Eight per-dataset taxon tables (species, taxa_rank, phyto_taxon, zoodb_taxon,
zooscan_taxon, bird_mammal_species, bird_mammal_behavior, obs_freq) are replaced by
taxon (worms:/itis: keys), dataset_taxon (per-dataset crosswalk) and taxon_group, and
obs_freq becomes obs_attribute (size/stage frequencies + behaviour). 22 → 17 tables.
Consumers: the consumer contract rekeyed from species_id to taxon_key.
