Temporal-based date and time utilities with timezone support and polyfill integration

// ANSI SQL / ODBC timestamp literal: space-separated (never "T"), always
// zero-padded (unlike RFC 2822's lenient 1-2 digit day), with an optional
// fractional-seconds component. This checks *shape* only — `parseSql` still
// hands the extracted string to `Temporal.PlainDateTime.from` for real
// calendar validation, same as GMT's other `isValid*` + `Temporal.*.from`
// pairs.
