v3.0.0-alpha.1

3.0.0-alpha.1 (2026-07-06)

• feat(temporal)!: upgrade @js-temporal/polyfill to 0.5.1 (ade19d5), closes js-temporal/temporal-polyfill#357

BREAKING CHANGES

• getNowInCalendar now returns a plain CalendarDate
  object ({ year, month, day, eraYear? }, src/types.ts) instead of a
  Temporal.ZonedDateTime. This removes Temporal from the public
  interface entirely and matches convertFromIso8601/convertToIso8601's
  existing return shape. Code that only read .year/.month/.day/.eraYear
  needs no changes; code that called Temporal methods on the result
  needs to re-derive another date via getNowInCalendar/convertFromIso8601
  instead of calling .withCalendar()/.startOfDay() on the previous
  result.
