docs: switch infrastructure to local PostgreSQL + home Docker server (no Vercel/Neon)

 - Next.js full-stack: single repo for marketing + web app via API routes
 - Email-link signing (no client account): lowest friction for clients; standard in real estate
 - utahrealestate.com forms scraping: AVOID — violates ToS; use manual PDF upload instead
+- Infrastructure: local PostgreSQL (Docker) + local `npm run dev`; no Vercel, no Neon, no cloud storage — home Docker server is eventual target
 - [Phase 01-foundation]: Lazy Proxy singleton for db/index.ts prevents neon() crash during Next.js build when DATABASE_URL absent
 - [Phase 01-foundation]: next-auth pinned to exact version 5.0.0-beta.30; middleware.ts at project root not src/; force-dynamic on auth route
 - [Phase 01-foundation 01-02]: PasswordField extracted as co-located client sub-component — keeps login page.tsx as pure server component

 - Phase 6 (Signing Flow) warrants a /gsd:research-phase before planning — JWT one-time enforcement + ESIGN/UETA audit + mobile touch has edge cases
 - DNS (SPF/DKIM/DMARC) for teressacopelandhomes.com must be configured before any signing link reaches a real client (Phase 6 acceptance criterion)
 - Exact WFRMLS required IDX disclaimer text must be obtained directly from WFRMLS before listings feature ships (Phase 2)
-- Neon + Vercel provisioning required before runtime auth flow can be tested end-to-end
+- WFRMLS vendor enrollment takes 2-4 weeks — start process immediately, build Phase 2 listings with mock data while waiting (moved from Blockers)
