kenat 2.0.0

A comprehensive Ethiopian calendar library for Dart. Includes date conversions, holidays, fasting, Bahire Hasab, and Geez.

2.0.0

• Rewrote the Orthodox saints data model to match the upstream nigs.json schema exactly (day-keyed, flat entries), fixing MonthGrid so Christian-mode calendars correctly gate saints by negs/showAllSaints instead of always showing every saint.
• Fixed MonthGrid's weekStart default (Sunday → Monday, matching the JS/TS reference) and made an invalid weekdayLang throw InvalidGridConfigError instead of silently defaulting.
• Fixed KenatError.toJson()'s type field, which previously always reported 'KenatError' regardless of the actual error subclass.
• Fixed the broken gregorianToHijri stub, which previously returned nonsense values.
• Added the distance-to-date API: distanceTo, distanceFromToday, Kenat.distanceToHoliday, Kenat.formatDistance, Kenat.generateDateRange.
• Added Gregorian-calendar rendering: calendar: 'gregorian' support in format/getDate/toISOString, plus formatGregorianStandard/WithWeekday/WithTime and toGregorianISODateString.
• Added static Kenat.getStaticMonthCalendar/Kenat.getYearCalendar, and a console printThisMonth() (backed by a new render module).
• Added getDate, isSameMonth, isSameYear, toJson, isHoliday, and startOf/endOf('year').
• Fixed setTime to always return a new instance instead of mutating in place, and corrected startOf('day')'s time value.
• Corrected the Ramadan fasting description text and removed an undocumented Islamic-holiday-date fallback that had no basis in the reference implementation.
