dsh_workflow

把 DSH 的一次性多 Agent 排程升級為可生成、可儲存、可治理、可觀察、可恢復的 Workflow 層：完整參考 KodaX workflow 設計能力，基於 Cordis、ctx.subagents、Session、後臺 jobs、審批等 DSH 機制獨立實現——命名/發現/生成/複用/暫停恢復/重跑續跑/持久證據/成本記錄與治理，零核心 patch 的 bundle 形態。

Upgrades DSH's one-shot multi-agent dispatch into a Workflow layer that is generatable, saveable, governable, observable and resumable: a KodaX-workflow-inspired reimplementation on DSH's own Cordis, ctx.subagents, sessions, background jobs and approvals — naming, discovery, generation, reuse, pause/resume, rerun/continue, persistent evidence, cost tracking and governance as a zero-core-patch bundle.
