Backend:
- New chatbot.tools.ts: 4 tools (get_server_stats, get_top_channels,
get_recent_activity, get_top_flagged) with real DB executors
- chatbot.service: agentic loop — stream:true, parse SSE, execute
tool_calls, feed results back, up to 4 rounds
- controller: resolve userId from X-User-Id header (no-login device
uuid) with auth middleware precedence; history/clear scoped per user
Frontend:
- use-chatbot-user: mint UUID in localStorage, send as X-User-Id
- chatbotApi.send/getHistory/clearHistory accept userId header
- client.ts: apiRequest supports custom headers per call
- provider: history load + send + clear keyed to device user id
