v1.4.0

What's Changed

• Added ValidationResult helpers: errorsByKey (errors grouped by field) and firstErrorFor(key).
• Added validateAndThrow / validateAndThrowAsync, throwing a LucidValidationException with all failures.
• Added numeric inclusiveBetween / exclusiveBetween validators (previously only available for DateTime).
• Added validUrl, length(min, max), isInEnum and precisionScale validators (each with an OrNull variant).
• Added withMessage, withErrorCode and withName for fluent, chained customization of the previous rule.
• Added asynchronous validation: mustAsync, mustWithAsync, useAsync and LucidValidator.validateAsync.
• Added ruleForEach to validate each item of a collection inline (without a dedicated validator class).
• Added rule sets via ruleSet(name, () {...}) and validate(entity, ruleSets: [...]).
• Added include to compose/reuse validators of the same entity type.
• Added unless (the inverse of when); when and unless now compose.
• Added normalize to sanitize a value before validation (e.g. trim/lowercase) without mutating the entity.
• Added switchOn for polymorphic/branching validations based on discriminator values (e.g. enums, Strings, ints).
• Added LucidValidator.inline factory constructor to build validators on the fly without subclassing.
• Added rulesForField and rulesForFieldAsync to evaluate and inspect the status of all rules on a specific field (e.g. for password checklist widgets).
• Added getExceptions and getExceptionsByKey to directly retrieve raw lists of validation exceptions.
• Added use and useAsync builders to manually construct custom rules with full control over the created ValidationException.
