v0.8.2 — 周期任务完成策略与 DSH V4 兼容

0.8.2

修复与改进

• DSH 0.1.7-rc.2 / V4 会话格式兼容：执行开场消息改用看板自身的 producer-owned dsh-taskboard 来源，修复手动和定时任务在首轮因 format v4 message requires a producer-owned source kind 而失败的问题（#34、#36；PR #33）。感谢 @weibaohui 提交并合入此修复。
• 周期任务完成策略（#35）：新增「完成后新建待办」（默认）与「完成后移回待办」选项。由宿主在结算时落实策略，不再依赖 agent 是否自行变更状态。
• 默认策略会将本轮卡片保留在待验收，并新建带 cron 的下一轮待办卡；选择「完成后移回待办」时复用原卡。模板、复制和后继卡会保留该策略；既有未设置策略的 cron 任务也采用默认的新建待办行为。
• 开发依赖统一升级到 DSH 0.1.7-rc.2。

验证

npm run typecheck、构建、host smoke test、npm test（351/351）和 git diff --check 均已通过。

Fixes and improvements

• DSH 0.1.7-rc.2 / V4 session-format compatibility: execution framing now uses the board's producer-owned dsh-taskboard source, fixing opening-turn failures with format v4 message requires a producer-owned source kind for both manual and scheduled work (#34, #36; PR #33). Thanks to @weibaohui for contributing and merging this fix.
• Periodic completion policies (#35): adds Create a new todo after completion (the default) and Return to todo after completion. The host enforces the policy during settlement instead of relying on an agent's status transition.
• By default, the completed round remains in review and a fresh cron-bearing todo successor is created. Choosing return-to-todo reuses the original card. Templates, copies, and successors retain the choice; existing cron tasks with no explicit policy use the new default as well.
• Development dependencies are aligned to DSH 0.1.7-rc.2.

Verification

npm run typecheck, build, host smoke test, npm test (351/351), and git diff --check all passed.
