feat: scaffold Phase 0 project infrastructure

Backend (Rust):
- Initialize Cargo workspace with strict clippy lints
- Set up 9 module stubs (auth, core, conversation, ai, tools, email, notifications, storage, audit)
- Implement API layer with RFC 7807 ProblemDetails error handling
- Add database infrastructure (sqlx pool, migrations, TestContext with postgresql_embedded)
- Implement Axum HTTP server with /healthz and /readyz health check endpoints
- Add Event Bus (tokio broadcast channel) with DomainEvent enum
- Create xtask subproject for future API type generation
- Add UUID v7 ID generation utility

Frontend (Vue):
- Initialize Vite 8 beta (Rolldown) + Vue 3 + TypeScript strict mode
- Configure ESLint (oxlint + eslint) with zero warnings policy
- Set up openapi-fetch + openapi-typescript for API contract
- Create AppLayout and AuthLayout with Vue Router guards
- Add base UI components (BaseButton, BaseInput, BaseCard)
- Add useAuth composable skeleton

Infrastructure:
- Add docker-compose.dev.yml (PostgreSQL 16 + MailHog)
- Expand Makefile with dev-up, lint, test targets (pnpm)
- Add GitHub Actions CI (backend + frontend + OpenAPI validation)
- Add .env.example with all environment variables
