Initial Release

Key Definition

• key() / unkey(): Define and remove keys from data frames

Row Identity

• add_id() / remove_id(): Add/remove stable UUIDs
• has_id() / get_id(): Query ID status
• extend_id(): Fill missing IDs after binding
• make_id(): Create composite IDs from columns
• bind_id(): Combine data with ID handling
• check_id() / check_id_disjoint(): Validate ID integrity
