Temporal Calendar Protocol implementation for Hijri calendar via hijri-core. Provides HijriCalendar base class, UaqCalendar (UAQ engine), FcnaCalendar (FCNA engine), and convenience singletons uaqCalendar/fcnaCalendar. Calendar protocol: year, month, monthCode, day, daysInMonth, daysInYear, monthsInYear, inLeapYear, dayOfWeek, dayOfYear, weekOfYear, daysInWeek, dateFromFields, yearMonthFromFields, monthDayFromFields, dateAdd, dateUntil, mergeFields. dateAdd applies year/month increments in Hijri coordinate space (correct semantics for variable-length lunar months), then applies days/weeks in ISO space. Day-of-month clamped on month boundary changes. 18 ESM + 8 CJS tests passing. Dual CJS/ESM build.
