shinchan-zhai	4fa375771d	feat(agent): LLM tool-calling for auto trade execution ... - New agent/tools.go: defines LLM tools (execute_trade, get_positions, get_balance, get_market_price) - thinkAndAct now uses CallWithRequestFull with tool-calling loop (max 5 rounds) — LLM autonomously decides when to call tools - Trade safety: execute_trade creates pending orders requiring user confirmation ('确认 trade_xxx' / 'confirm trade_xxx') - Pending trades expire after 5 minutes - System prompt updated with tool usage instructions and safety rules - Both paths work: regex shortcut ('做多 BTC 0.01') and natural language ('帮我开一个BTC多单') via LLM tool calling - Fallback: if tool-calling fails, degrades to plain LLM call	2026-03-23 02:27:25 +08:00
