- Dropdown: aria-multiselectable, drop dead aria-labelledby, ArrowUp opens panel
- Dirty-state: NewTaskModal tracks enabledWorkflowSteps so toggles trigger discard prompt
- TaskForm: reset optionalStepsLoading on the no-workflow early return
- Node editor: pass plugin step templates into the optional-steps panel (both layouts)
- FNXC requirement comments on the new optional-steps components
Add WorkflowOptionalStepsDropdown — a controlled, portal-rendered multi-select
(listbox a11y, keyboard nav, committed 'Steps: N selected' label matrix,
render-nothing empty state) shared by the quick-add card and (next) the full
modal. Swap InlineCreateCard's inline chip toggles for it; the fetch/seed/submit
wiring is unchanged. Remove the now-unused chip CSS.
