/// Diesel changeset used by `address_book_update` so the three mutable columns
/// (`name`, `address`, `note`) are written in a single UPDATE statement. Each
/// field is wrapped in `Option` so callers can pass `None` to leave the column
/// untouched without issuing a separate query per field.
///
/// `note` is double-`Option` deliberately: the outer `Option` controls whether
/// the field is part of the UPDATE at all, and the inner `Option<&str>`
/// matches the nullable column so it can be set to `NULL` to clear a
/// previously-stored note.
///
/// `updated_at` is `dsl::now` (a zero-sized type, not `Option`) so every
/// UPDATE bumps the timestamp — matching the `StealthOutputUpdate` pattern in
/// `stealth_output.rs`. `dsl::now` cannot be wrapped in `Option` because it
/// is a SQL expression, not a value.
