Struct SubAgentMetrics 

pub struct SubAgentMetrics {
    pub total_llm_calls: u32,
    pub total_tool_calls: u32,
    pub total_input_tokens: u64,
    pub total_output_tokens: u64,
    pub total_llm_elapsed_ms: u64,
    pub total_tool_elapsed_ms: u64,
    pub llm_elapsed_ms_per_call: Vec<u64>,
}

子 Agent（SubAgent / Teammate）的 metrics 累加器

每个子 Agent loop 内部累加，Main agent loop 结束时读取并合并到 SessionMetrics。 使用 Arc<Mutex<SubAgentMetrics>> 实现多 Agent 并发安全写入。

Fields

total_llm_calls: u32

LLM API 调用次数

total_tool_calls: u32

工具调用次数

total_input_tokens: u64

输入 token 总数

total_output_tokens: u64

输出 token 总数

total_llm_elapsed_ms: u64

LLM 调用总耗时（毫秒）

total_tool_elapsed_ms: u64

工具执行总耗时（毫秒）

llm_elapsed_ms_per_call: Vec<u64>

每次非流式 LLM 调用的耗时（等同于整次调用耗时，非流式无 TTFT 概念）
