"""手工触发 LLM 错误告警。

用法：
    source ../.venv/bin/activate
    python tests/manual_trigger_fetch_loop_llm_error.py --scenario score
    python tests/manual_trigger_fetch_loop_llm_error.py --scenario immediate
    python tests/manual_trigger_fetch_loop_llm_error.py --scenario digest
    python tests/manual_trigger_fetch_loop_llm_error.py --scenario all

场景说明：
- score: 走 fetch_loop -> run_fetch_job -> score_batch，触发评分错误通知
- immediate: 走 run_fetch_job -> generate_immediate_push，触发即时推送生成错误通知
- digest: 走 run_push_job -> compose_digest，触发汇总生成错误通知
- all: 依次触发以上三类真实通知
