docs(plan): self-serve signup & onboarding implementation plans
Adds two phase plans alongside the spec at
docs/superpowers/specs/2026-05-05-self-serve-signup-onboarding-design.md:
- Phase 1 (backend foundation, 26 tasks across 8 sub-phases A-H):
schema migrations, subscription model + new guards, BillingService,
Stripe webhook handler extension, OAuth callbacks, email verification
auto-send + email-match enforcement, account-invite extensions,
GET /billing/state, pilot user backfill. Step-by-step granularity
with full code blocks per writing-plans skill.
- Phase 2 (frontend + cutover, 21 tasks across 7 sub-phases I-O):
Phase-1-deferred endpoints, useBillingStore + hooks + gating
components, register redesign + OAuth buttons + accept-invite,
welcome wizard, dashboard redesign, pricing page + contact-sales,
beta-signup deprecation, cutover. Higher-altitude — defines
contracts, acceptance criteria, integration tests; leaves
component-detail decisions to implementer.
Each phase ends in a mergeable PR. Cutover is gated behind
SELF_SERVE_ENABLED + VITE_SELF_SERVE_ENABLED. Execution deferred to
a future session.
