Initial commit: EGBE chatbot template

Stripped from vercel/chatbot (Apache 2.0):
- Dropped @vercel/* packages and AI Gateway
- Removed artifacts feature (code/text/sheet/image side panel)
- Switched AI provider to @ai-sdk/openai-compatible -> EGBE LiteLLM
- Replaced Vercel Blob upload with data URLs
- Dropped Redis resumable streams and rate limiter (in-memory now)
- Added Dockerfile (Next.js standalone) + entrypoint that runs migrations
- Wired DATABASE_URL, EGBE_AI_API_URL/KEY, NEXT_PUBLIC_BASE_URL for app-deploy.sh

+# EGBE Chatbot Template
+
+Next.js chatbot wired to the EGBE LiteLLM proxy. Based on [vercel/chatbot](https://github.com/vercel/chatbot) (Apache 2.0), stripped of Vercel-specific bits and rewired for our infra.
+
+## Stack
+
+- **Next.js 16** (App Router, standalone output)
+- **AI SDK** + `@ai-sdk/openai-compatible` → routes to `EGBE_AI_API_URL` (our LiteLLM)
+- **NextAuth** (credentials + guest)
+- **Drizzle ORM** + Postgres (DB gateway)
+- **shadcn/ui** + Tailwind
+
+## Available models (via LiteLLM)
+
+`claude-sonnet`, `claude-haiku`, `gpt-5.4`, `gpt-5.4-mini`, `kimi-k2.6`, `minimax-m2.7`, `qwen3-coder`.
+
+Edit `lib/ai/models.ts` to add or remove.
+
+## Deploy (from inside an OpenClaw instance)
+
+```bash
+${SKILLS_DIR}/scripts/app-deploy.sh <slug> chatbot-template
+```
+
+`app-deploy.sh` auto-injects:
+- `DATABASE_URL` (per-app Postgres)
+- `EGBE_AI_API_URL`, `EGBE_AI_API_KEY` (instance LiteLLM key)
+- `NEXT_PUBLIC_BASE_URL` (the deployed `*.p.egbe.app` host)
+
+You also need `AUTH_SECRET` — set it via `APP_ENV_JSON`:
+
+```bash
+APP_ENV_JSON='{"AUTH_SECRET":"'$(openssl rand -base64 32)'"}' \
+  ${SKILLS_DIR}/scripts/app-deploy.sh mychat chatbot-template
+```
+
+## Local dev
+
+```bash
+cp .env.example .env.local
+# fill in DATABASE_URL, EGBE_AI_API_KEY, AUTH_SECRET
+pnpm install
+pnpm db:migrate
+pnpm dev
+```
+
