Dreaming 孤儿会话 — 磁盘膨胀与网关启动缓慢

# 会话存储总大小
du -sh ~/.openclaw/agents/main/sessions/

# 统计会话相关目录数
find ~/.openclaw/agents/main/sessions/ -maxdepth 1 -type d | wc -l

# 列出最大的 dream-temp 目录
find ~/.openclaw/agents/main/sessions/ -name 'dream-temp-*' -type d -exec du -sh {} \; | sort -hr | head -20

# 先停止 gateway
openclaw gateway stop

# 预览孤儿候选（14 天以上，dream-temp 前缀）
find ~/.openclaw/agents/main/sessions/ \

# 移到隔离区（比 rm 更安全）
mkdir -p ~/openclaw-session-quarantine
find ~/.openclaw/agents/main/sessions/ \
  -maxdepth 1 -type d -name 'dream-temp-*' -mtime +14 \
  -exec mv {} ~/openclaw-session-quarantine/ \;
