dsh-matt-skills-flow: Transforming Matt Skills into a recoverable engineering workflow

`dsh-matt-skills-flow` is an unofficial DeepSeek Harness (DSH) plugin designed to transform `mattpocock/skills` into a persistent, recoverable engineering workflow. It solves the problem of lost task state after session interruptions by unifying the management of key stages such as Flow, Skill snapshots, Decisions, Specs, Ticket graphs, Lane execution, Review, and Manual Acceptance, thereby achieving continuous tracking of task states. Core features include: snapshotting installed Skills when creating a Flow; interactively recording decisions and approving Specs; publishing dependency-aware Ticket graphs (supporting local Markdown or GitHub Issues); and creating isolated Lane branches to run [skills].
