unwrapOk had zero consumers in apps/ or libs/ since ADR-0006 shipped it. The one call site the finding named already satisfies the ADR's real rule (call the real parser, never a cast) with an inline guard, so adding a manufactured first caller was not the better fix. This commit deletes the helper and its file, and updates the one doc sentence that named it. The finding's call site is unchanged. See rb-33.md for the full adopt-or-delete reasoning.
