Added new identity fields:
nails (shape / length / style)
nail_color (color / finish)
Updated FIELDS_ORDER to include nails and nail_color at the end
Extended INPUT_TYPES with new selectable options for nails and nail_color
Updated mix() logic to process and include new fields in identity generation
Ensured compatibility with:
TRAITS format
PRESETS format
Legacy identity structures
Preserved deterministic signature generation including new fields
Maintained backward compatibility with existing identity.json files
This change improves identity consistency and enhances fashion/editorial detail
without polluting scene-level JSON prompts.
