 * Serializes a value to a canonical JSON string as defined by
 * [RFC 8785 (JSON Canonicalization Scheme)](https://www.rfc-editor.org/rfc/rfc8785).
 *
 * - Object keys are sorted recursively by UTF-16 code unit comparison.
 * - Primitives are serialized per ECMAScript rules (no trailing zeros on numbers, etc.).
 * - No whitespace is inserted.
 *
 * @example
 * ```ts twoslash
 * import { Json } from 'ox'
 *
 * const json = Json.canonicalize({ b: 2, a: 1 })
 * // @log: '{"a":1,"b":2}'
 * ```
 *
 * @example
 * ```ts twoslash
 * import { Json } from 'ox'
 *
 * const json = Json.canonicalize({ z: [3, { y: 1, x: 2 }], a: 'hello' })
 * // @log: '{"a":"hello","z":[3,{"x":2,"y":1}]}'
