Implements the complete AI flow builder feature using a guided 4-stage wizard (Foundation → Scaffold → Branch Detail → Review & Assemble). AI assists at bounded points using Claude Haiku for cost-efficient structured JSON generation (~$0.01-0.03/flow). Backend: new models (ai_conversations, ai_usage), Alembic migration, quota enforcement with billing anchor, Anthropic API integration with prompt caching, tree validation, conversation CRUD with 24h TTL, APScheduler cleanup job, 5 API endpoints, Pydantic schemas. Frontend: TypeScript types, API client, Zustand store for wizard state, 7 components (modal, step indicator, foundation form, branch selector, branch detail view, tree preview, quota display), MyTreesPage integration with "Build with AI" button (hidden when AI not configured). Tests: 14 validator unit tests + 11 endpoint integration tests with mocked Anthropic (zero real API spend). All 25 tests passing. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
