"""review_needed_watchdog.py 修复（2026-08-19 老莫：P1 架构收敛）
原 bug：strategy_lifecycle 把 status=review_needed 写入 DB（holding_strategies.status，
经 per_stock_reassess result.status 写回），但本 watchdog 却读废弃的 decisions.json →
永远空跑，DB 里 review_needed 没人消费（写入方与消费方脱节）。
修复：改读 DB（holding_strategies.status='review_needed'），对接 strategy_lifecycle 写入；
XMPP 走 alert_helper 统一网关（分级 ACTION）。
