add plans from usability testing: onboarding v2, notifications, live editor

Onboarding UX v2 supersedes the original plan — reworks setup into a
single guided journey with progress bar, forgiving validation, and
contextual prompts for skipped steps.

Notification overhaul replaces floating toasts with inline feedback
and persistent top banners (110+ flash messages audited).

Live site editor is a design exploration for on-site editing with
contenteditable text and live CSS variable injection.

Also adds SEO settings and multiple providers to the roadmap.
