d312e6d Thanks @jviide! - feat: always normalize custom errors

Custom errors listed in issue lists (ValitaError.issue and ValitaResult.issue) are now always normalized to match the type { code: "custom_error", path: (string | number)[], message?: string | undefined }.

e66a42e Thanks @jviide! - Allow passing a type to .chain()

The .chain() method of types now accepts other types as-is:

v.string() // Accept strings as input,
  .map((s) => Number(s)) // then parse the strings to numbers,
  .chain(v.literal(1)); // and ensure that the parsed number is 1.

The parsing mode is propagated to the chained type:

const example = v.unknown().parse(v.object({ a: v.number() }));

example.parse({ a: 1, b: 2 }, { mode: "strip" });
// { a: 1 }

The .nullable() method now supports default value functions_similarly to .optional().
