Steps to reproduce

Following metrics are missing in agent-chat mode of tencent trace.

• gen_ai.client.operation.duration
• gen_ai.server.time_to_first_token
• gen_ai.streaming.time_to_generate

✔️ Expected Behavior

Agent-chat traces should have the same completeness as advanced-chat workflow traces:

• Complete metrics collection
• Dedicated LLM span with full attributes
• Correct streaming detection

❌ Actual Behavior

• Streaming requests are incorrectly marked as stream="false"
• No LLM child span is created (unlike workflow LLM nodes)
