fix: 速度胶囊每轮只显示一次 + 技能调用按 run 合并统计

速度胶囊：原本每条 AI 消息都渲染，agentic 多轮 LLM 调用会出现多个胶囊。改为只在每轮 turn-final 消息（下一条 human 之前的最后一条 AI 消息）显示。

技能统计：tool_call_metrics 改为按 (run_id, skill_name) upsert 合并——同一 run 内同一技能的多次调用/重试合并为一行；任一成功即记成功，全部失败则记一行 error 并累积所有报错信息；非技能调用不受影响。

Any success in the run wins (a skill that failed then finally succeeded is recorded as one `success`); a skill that only ever failed yields one `error` row whose `error_message` accumulates every attempt's message; durations are summed. Non-skill tool calls, and skill calls with no `run_id`, keep one row each. The read→merge→write is guarded by a per-event-loop `asyncio.Lock`.

The prefix is tagged onto the first human message's `additional_kwargs['prompt_prefix']` by the Gateway (`app.gateway.services`) and prepended to content here at call time, so the persisted/displayed message stays prefix-free
