time_ 1cdd80f51b feat: align RU validation, error contract, and generator runtime templates
Wire DSL-derived field labels, safe API error JSON (string|string[]), decimal/enum DTO fixes, and client dataProvider without comma-splitting. Add generation/templates/runtime as canonical source copied on generate; extend AID bundle, prompts, validation gate, and docs.
