v5.1.0

Changelog: v5.0.0...v5.1.0

• A prototype is preserved when an object is cloned:

class Foo {
  hello = 42
}

const input = new Foo();
const output = d.object({}).strip().parse(input);

input === output
// ⮕ false

output instanceof Foo
// ❌ Before ⮕ false
// ✅ After  ⮕ true

• Simple plugin imports:

import * as d from 'doubter/core';
import 'doubter/plugin/array-essentials';

d.array().nonEmpty();

• readonly() support for ArrayShape, ObjectShape, RecordShape, MapShape, and SetShape:

d.array(d.string()).readonly();
// ⮕ Shape<string[], readonly string[]>

• Enhanced formatting of issue messages and validation error messages.

• Multiple performance optimizations.
