v0.8.6 — 完善定期会话关于复用会话的逻辑

v0.8.6

中文

• 完善定期会话关于复用会话的逻辑：cron 定期任务现在可明确选择“每次新建会话”或“首次新建会话，后续复用”，也仍可指定当前项目中的既有会话。
• 复用策略不再受“完成后移回待办”或“完成后新建下一轮待办卡”影响；选择“首次新建、后续复用”时，首轮会话会安全传递到下一周期卡。
• 一次性定时任务维持原有的单次执行语义；已有定期任务保持此前的自动续用行为，升级不会静默改变配置。

English

• Improved periodic session reuse logic: cron tasks can explicitly choose “new session every time” or “create first, then reuse,” while still allowing selection of an existing session from the current project.
• The reuse policy no longer depends on whether periodic completion rearms the current card or creates a successor; create-then-reuse safely carries its first session into the next period card.
• One-shot tasks retain their original single-run semantics, and existing periodic tasks retain their prior automatic-reuse behavior without silent configuration changes.
