feat(components): add CustomAmountEditor, bump to 0.2.0

Extract the shared presets-plus-custom editor card — tonal surface with the
connected shape, an optional single-choice unit toggle, and an amount field
with a live preview + confirm — used by the reminder, agenda-range and snooze
pickers into one reusable, presentational component.

+ * The expanded "Custom" editor card shared by the family's presets-plus-custom
+ * pickers (reminder lead time, agenda range, snooze delay). A tonal surface with
+ * the connected-shape that meets the "Custom" row above it (tight top corners,
+ * full bottom), holding — top to bottom — an optional single-choice unit toggle,
+ * then a row of [DialogAmountField] + a live [preview] of what the amount
+ * resolves to + a tonal confirm.
+ *
+ * Purely presentational: the caller owns the amount/unit state and computes
+ * [preview] and [confirmEnabled] from its own domain, so this component carries
+ * no units, ranges, or strings of its own. Pass [unitLabels] empty for an
+ * amount-only editor (no toggle row). [onConfirm] fires on the confirm button.
