Release v2.20.0 (#286)

Release 2.20.0.

**Added**
- Long-press an event's title, location or description to copy it ([#195]).
- Settings → About lists the open-source projects Calendula ships, with
  copyright holder, licence and a link to each project's source ([#281]).

**Changed**
- Week and day view seat every hour in its own rounded cell instead of drawing a
  separator line across the column; an on-the-hour event fills its cell rather
  than overhanging the seam ([#113]).
- Event titles run to the edge of their chip in all three grid views — no
  ellipsis. RTL keeps it, where clipping would cut the start of the title
  ([#164]).
- Month events show their start time where the chip is wide enough, and event
  times across month, week and day are set in a regular weight ([#219]).
- An invitation you haven't answered is drawn as an outline; declined events
  keep their filled, struck-through chip and now sort last in the month view
  ([#230]).
- The top-bar title falls back to a shorter form instead of being cut off, and
  the bar's trailing edge lines up with the grid under it ([#165]).
- The jump-to-today button carries today's date and rolls over at midnight
  ([#220]).
- The quick-switch pill hides when there is nothing to switch between, and views
  can now be turned off down to a single one ([#150]).

**Fixed**
- A long location wraps and its card grows, instead of scrolling sideways out of
  sight ([#273]).
- The event form capitalizes sentences again; location stays uncapitalized,
  being as often a URL as an address ([#146]).
- A dragged block's floating copy wraps its time and title the way the block
  does, instead of clipping to one line while held ([#267]).

### Release preparation

`versionName`/`versionCode` → 2.20.0/22000, `CHANGELOG.md`'s Unreleased section
moved under a dated 2.20.0 heading, and a hand-written 497-character
`fastlane/metadata/android/en-US/changelogs/22000.txt`.

Six of the merged PRs had no CHANGELOG entry (#146, #150, #195, #230, #267,
#281); they are written up here. The existing #164 entry only described the
month view and did not mention the RTL exception — both corrected.

### Also here

`scripts/check_changelog_lengths.sh`, run in CI next to the reproducible-release
invariant. Play rejects a "What's New" over 500 characters, which would fail the
upload *after* the release had already shipped to F-Droid and Codeberg —
2.19.4 went out at 697. The script walks every locale, fails on the current
`versionCode` and only warns on the already-published files, of which 13 are
over the limit from when the pipeline auto-generated them from `CHANGELOG.md`.

Deviation worth naming: this does not fix those 13. They are published and Play
never re-reads them, so failing on them would paint every PR red for no gain;
`--strict` covers them if they are ever backfilled.

Follow-up filed as #285 — the store listing exists in only 4 of 12 locales and
its graphics still don't qualify for Play.

All twelve issues above are closed by their own PRs; this branch ships them.
