feat: Phase 0 walking skeleton — monorepo, API, web, ML stub
Sets up the full Phase 0 foundation:
- pnpm workspaces + turbo build graph; native module build approval
- packages/shared-types: HTTP contracts (Tip, Auth, Integrations, User)
- services/api: Express modular monolith with better-sqlite3/drizzle
- auth: Google OAuth2 + PKCE via openid-client v6, cookie sessions
- integrations: Todoist OAuth2 connect/disconnect, token vault
- recommender: RandomPolicy over Todoist tasks, feedback sink
- user: profile, consent capture, full account deletion (GDPR)
- apps/web: Next.js 15, three pages (sign-in → connect → tip)
- tip page: black canvas, hold-to-act gesture, action sheet
- PWA manifest + theme
- ml/serving: FastAPI stub implementing the POST /score contract
- infra: docker-compose (core/full profiles), Dockerfiles, CI skeleton
- .env.example with all required vars documented
