dsh-worktree-space: One Task, One Space: Parallel Work Across Branches

The DeepSeek Harness (DSH) plugin `dsh-worktree-space` adopts an "everything is a plugin" architecture and uses the worktree mechanism to physically isolate tasks across multiple repositories. The plugin places each task in an independent directory, creates a separate worktree for each repository on a unified branch, and allows the Agent session to work directly within the isolated space. Core features include task creation, automatic workspace registration, view management, adding repositories to tasks, and bilingual support. The plugin supports resolving conflicts through Git merging but does not create commits on the user's behalf. Installation requires Node.js >= 22.19.0 and the required DSH version, and it is suitable for complex, cross-repository development tasks.
