release: floret-kit 0.2.1

Adds components' `scrollable` opt-out on CollapsingScaffold (and its
FullScreenPicker passthrough), so a picker with more options than an
eagerly composed column can carry can drive its own LazyColumn.

+- **`components`** — `CollapsingScaffold` takes a `scrollable` flag (default
+  `true`, so every existing caller is unchanged). Set it to `false` when the
+  content brings its own scrolling container: the scaffold's own
+  `verticalScroll` composes each row up front and can't host a `LazyColumn`
+  (nesting a same-axis scrollable throws), which ruled out any surface with more
+  options than fit an eager pass. Opting out hands the content a plain column and
+  leaves the insets, IME padding and top-bar collapse as they were.
+  `FullScreenPicker` forwards the flag. Consumed by Calendula's ~600-entry
+  time-zone picker from 2.16.0.
