Caddy now owns ports 80/443 and reverse-proxies to the frontend
container (which was publishing 80 itself, conflicting with Caddy),
handling Let's Encrypt certificate issuance/renewal automatically.
Fix the Caddyfile's upstream name (it referenced a nonexistent "app"
service instead of "frontend") and update the Lightsail deploy guide's
HTTPS section to match this setup instead of the old manual-certbot
approach.
- Add backend/frontend Dockerfiles, nginx reverse proxy config, and
docker-compose.yml to run the app on AWS Lightsail; document the setup
in docs/deploy-lightsail.md. Fix a .gitignore path anchoring bug that
left backend/knowledge_base/web_search/ untracked instead of ignored.
- Summarize web search results into structured Markdown via LLM before
saving them to the local knowledge base, and support regenerating
existing entries from their source URLs (backend/app/core/memory_kb).
- Downgrade vite to ^6 to match @vitejs/plugin-vue's peer dependency
range, fixing a failing `npm ci` (found while testing the Docker build).
