### Added
- Give an event its own time zone. A new Time zone field (under "more fields" in
  the event form) pins an event to a specific zone, so a call set for 8:00 AM in
  New York stays 8:00 AM in New York wherever you open it, and keeps tracking
  that zone across daylight-saving changes. The form shows the local equivalent
  under the times, and the event's details keep your local time first with the
  original noted beneath. Pick a zone from a searchable full-screen picker — by
  city, IANA id, or abbreviation like "CEST". All-day events stay date-anchored
  and carry no zone ([#31]).
- Put the "jump to today" button in the toolbar. A new Today button in toolbar
  setting (Settings → Appearance, off by default) swaps the floating corner
  button for a permanent today icon in the top bar — always there, matching the
  familiar calendar-app pattern. Leave it off to keep the floating button ([#60]).
- Show the app as "Calendar" in your launcher. A new App name setting
  (Settings → Appearance) switches the launcher label from "Calendula" to the
  generic "Calendar" for anyone who prefers it — handy on launchers that can't
  rename apps themselves. Only the launcher name changes; your home-screen icon
  may move to a new spot after switching ([#44]).

### Changed
- Dates in the Month, Week and Day title bars now follow your language and
  region instead of one hardcoded layout. Every date was rendered in a fixed
  German-style order with a trailing dot on the day number, whatever your
  settings: US English showed "Fri, 17. Jul 2026" where it should read
  "Fri, Jul 17". The Agenda view already formatted correctly, so the two
  disagreed about the same date. All four views now share one formatter, and the
  day/month order, the separators and the ordinal all come from your locale —
  so English-in-Germany reads "Fri, 17 Jul" and English-in-the-US "Fri, Jul 17",
  each correct for where you are ([#60]).
- The title bar drops the year while you're in the current one — "July" rather
  than "July 2026". The year reappears the moment you page out of the current
  year, which is when it tells you something you didn't already know.
- The Week view's title now names the month instead of spelling out the day range.
  "24. Jun – 31. Jun" restated the day numbers already printed in the column
  headers right below it, in the widest string in the bar. A week that straddles
  two months keeps the outgoing month until it is fully gone ([#60]).
