rskit-validation — Fluent Input Validation

Fluent field-level validator that collects errors and converts to AppError.

Features

• Fluent builder API — chain validators on a single Validator instance
• String checks: required, min_length, max_length, email, url, pattern (regex)
• UUID checks: required_uuid, optional_uuid
• Numeric range via in_range<T>
• Temporal checks: before, after (ISO-8601 strings)
• Enum membership via one_of<T>
• Custom boolean predicates via custom
• Accumulates all FieldErrors, then converts to AppError::invalid_input on validate()
