Subject: [PATCH] fix: normalize password prompt empty submit to empty string
 (#560) The password prompt resolved to undefined on empty submit instead of
 empty string. Normalize the value on finalize to match the text prompt and
 the documented Promise<string | symbol> return type.

+Fix `password` prompt resolving to `undefined` on empty submit. It now normalizes an empty submission to `""`, matching the `text` prompt behavior and the documented `Promise<string | symbol>` return type.
