dsh-worktree-flow: Multi-Repository Feature Workspace Plugin

This DSH plugin creates multi-repository feature workspaces to address issues in multi-repo development, such as writing code to the wrong location and branch confusion. It binds repositories into “sets,” creates an independent Git worktree for each feature, shares the same feature branch, and automatically registers as DSH workspaces to provide sandbox isolation. Core features include branch pre-creation, identity description injection, environment diagnostics, and batch component binding. The plugin supports custom branch types and real-time shared documentation, making it suitable for integrated multi-component development. Note permission restrictions in Windows environments and Node.js version requirements.
