feat: add automation, reminders, notifications, msg search, session export, image analysis, host exec, PWA, Docker, E2E, CI/CD

- Automation: rules CRUD (in-memory store + API)
- Reminders: CRUD (in-memory store + API)
- Notifications: push interface for future push server
- Message search: API endpoint with DB-backed query
- Session export: /sessions/:id/export → Markdown
- Image analysis: API stub for multimodal LLM
- Host exec: API stub for Docker sandbox
- PWA: manifest.json + service worker
- Docker: Dockerfile + docker-compose.yml
- E2E: Playwright test scaffold
- CI/CD: GitHub Actions workflow (go test + tsc)
