fix(edit): curate the CalDAV colour picker (#22)

CalDAV sync adapters (DAVx5) publish all ~147 CSS3 named colours into
CalendarContract.Colors, so the event-colour picker showed a full screen
of alphabetically-scrambled, partly duplicated swatches.

Curation now runs in the space the picker actually paints — every swatch
is softened through pastelize, which pins lightness and caps saturation,
so the raw palette's lightness axis is invisible on screen. Judging
distinctness there: colours that paint identically collapse to one
(folding aliases, dark/light shades of a hue, and the neutrals together),
oversized palettes drop washed-out neutral-origin tints and thin by CIE76
ΔE in painted Lab, and survivors sort continuously by painted hue with the
wheel cut at its single widest gap. The CSS3 dump lands at ~33 distinct,
rainbow-ordered swatches; small hand-picked palettes (Google's) pass
through untouched. Every surviving swatch keeps its provider colour key so
picks still round-trip through sync.

This revives work stranded on fix/caldav-color-picker (never merged) and
adapts it to the floret-kit extraction of pastelize: the curation's
painted-space transform now lives self-contained in domain/pastelArgb as a
mirror of floret's pastelize shaping, rather than the two sharing one
function.

+## [Unreleased]
+
+### Fixed
+- A tidy colour picker on CalDAV calendars. For calendars synced by a CalDAV
+  app (such as DAVx5), the event colour picker showed every colour the account
+  publishes — nearly 150 swatches in alphabetical order, many of them
+  duplicates or near-identical shades. The picker now shows only visually
+  distinct colours, arranged as a rainbow; near-duplicate shades and the
+  washed-out neutrals are folded away so no two swatches look alike. Picked
+  colours still sync exactly as before, and calendars with hand-picked
+  palettes (like Google's) are unaffected. Thanks to @ptab for the report
+  ([#22]).

+ * Sync adapters differ wildly in what they publish: Google exposes a
+ * hand-picked two-dozen set, while CalDAV adapters (DAVx5) dump all ~147 CSS3
+ * named colours — including exact-value aliases (aqua/cyan, the gray/grey
+ * spelling pairs) and dozens of visually indistinguishable whites and grays
+ * (#22).
+ *
+ * Crucially, curation runs against the colour the picker actually *paints*, not
+ * the raw provider value. The picker softens every swatch through [pastelArgb]:
+ * it pins lightness to a constant and caps saturation, so the raw palette's
+ * lightness axis is invisible on screen. Two raw colours that look different —
+ * a navy and a mid blue — paint as one swatch, and every neutral (black, the
+ * grays, white) paints as the same pale tint. Judging distinctness in raw
+ * space, as before, left near-identical painted swatches and stranded the
+ * neutrals as a run of look-alike "pinks" at the end of the grid.
+ *
+ * Three steps, all in painted space:
+ *  1. Collapse swatches that paint identically to one (alphabetically-first key
+ *     wins, deterministically) — this folds aliases, dark/light shades of a
+ *     hue, and all the neutrals together.
+ *  2. Oversized palettes (> [CURATION_TRIGGER_SIZE]) drop the washed-out
+ *     neutral-origin tints (painted chroma < [PASTEL_CHROMA_FLOOR]) and are
+ *     then thinned to visually distinct colours: most vivid first, a colour is
+ *     kept only when at least [MIN_DELTA_E] (CIE76, painted Lab) from every
+ *     colour already kept. Small palettes are already curated by their adapter
+ *     and pass through whole.
+ *  3. The survivors are ordered like a rainbow — continuously by painted hue —
+ *     with the wheel cut at its single widest empty gap so the one unavoidable
+ *     seam lands in dead space and no hue family is torn across both ends.
+ *

+Calendula es una aplicación de calendario moderna y de código abierto

+mediante DAVx5, Google, calendarios locales, suscripciones WebCal —
+aparece automáticamente, y los cambios que hagas se sincronizan de vuelta
+del mismo modo.
+
+Crea, edita y elimina eventos, incluidos los recurrentes con cambios
+acotados (solo este evento / este y todos los siguientes / toda la serie)
+y un sencillo selector de repetición. Calendula también entrega los
+recordatorios de tus eventos como notificaciones: toca una y estarás en
+el evento.
+
+Si quieres, muestra en tu calendario los cumpleaños, aniversarios y otras
+fechas especiales de tus contactos. Tú mismo lo activas; los contactos se
+leen solo en tu dispositivo, nunca se suben y nunca se modifican —
+Calendula solo refleja las fechas en calendarios locales que controlas
+por completo.
+
+El factor diferenciador es el diseño: auténtico Material 3 Expressive en
+toda la aplicación, con Dynamic Color, movimiento expresivo y formas
+expresivas.
+
+Privacidad: cero telemetría, sin analíticas, sin acceso a la red — tus
+datos nunca salen del dispositivo.
