validateJakarta

Registers a JakartaKandraValidator for T with install(Kandra) { ... }, running its Jakarta Bean Validation constraints before every save/update.

install(Kandra) {
    register(User::class)
    validateJakarta<User>()
}

Logs a WARN and skips registration if no Bean Validation provider (e.g. Hibernate Validator) is found on the runtime classpath, rather than failing plugin install.
