* fix: send_message_to_user cron 场景下 session 容错 (#7907) - LLM 在主动场景可能只传 session_id 而非完整三段式, from_str 失败时用 current_session 补全前两段。 Co-authored-by: Copilot <copilot@github.com> * fix: 限制 session 补全仅对裸 session_id 生效,避免误修带冒号的错误输入 (#7907) * feat: add session information to cron job payload Co-authored-by: Copilot <copilot@github.com> * fix: improve clarity and consistency of safety mode prompts Co-authored-by: Copilot <copilot@github.com> --------- Co-authored-by: Copilot <copilot@github.com> Co-authored-by: Weilong Liao <37870767+Soulter@users.noreply.github.com> Co-authored-by: Soulter <905617992@qq.com>
