root bd0f84c1f7 fix: deduplicate assistant content in multi-tool turns to prevent premature loop exit
- process.go: only emit resp.Content on the first tool call per batch,
  subsequent assistant messages use empty content (serialized as null)
- provider.go: MarshalJSON outputs null content when empty with tool_calls
  to comply with DeepSeek/OpenAI expected format
- output.go: update parameter interface (payload/type/meta) to match
  tool definitions (uncommitted from previous refactor)

【参数说明】
payload — 消息载荷必填。type=text 时直接填文字type=file/image 时填 URL 或路径
meta — JSON 对象,发送所需的元数据(可选,取决于通道是否需要路由信息)
type — 载荷类型(必填),枚举值见下方
【type 枚举】
- text — 文本消息
- voice — 语音消息
- image — 图片
- file — 文件
【meta JSON 格式】
由通道描述定义,通常包含:
- "group_id" 群号(群聊时必填)
- "user_id" 目标用户 QQ 号(私聊时必填)
- "reply_to" 回复某条消息 ID可选
示例: output_send__%s(payload="你好", meta="{\"group_id\": 123456789}", type="text")`, channel, desc, capStr, channel)
