phase-0: foundation, both apps boot end to end

Monorepo (pnpm workspaces) with two deployable apps and three pure packages. apps/api (Hono on Node): Zod validated env that fails fast and names the problem, Kysely factories for SQLite and Postgres chosen by DATABASE_URL scheme, portable migrations covering the whole SPEC section 5 schema, Better Auth with the four roles and seeded demo accounts, localized error envelope, /healthz and /readyz, graceful SIGTERM drain. Dialect specific SQL is confined to the two factories. apps/web (Next.js App Router): locale routed shell in es and en with a language switcher, sign in screen, and a runtime /api proxy so the browser only ever sees one origin and cookies stay first party. packages/i18n ships both catalogs complete; es is generated from COPY.md and a test re-derives it from the document on every run so it cannot drift. packages/contracts holds the Zod schemas and the typed client the web app uses. Verified: 43 vitest tests, 14 Playwright tests on mobile and desktop, typecheck and lint clean, migrate and seed from a clean database, sign in through the proxy with CSRF rejection of foreign origins. Not verified here: docker compose. This user has no access to the docker socket. RULES.md is absent from docs/, so packages/rules exports only RULES_VERSION and no tax rule, check digit or deadline was invented. See DECISIONS.md.
