Introducing the DeepSeek Harness Plugin: dsh-wsl-picker

The `dsh-wsl-picker` plugin for DeepSeek Harness (DSH) is designed to simplify access to the WSL filesystem by allowing users to directly browse the WSL root directory `/` and the `/mnt` mount point through the tool interface without additional steps. It belongs to the `dsh-wsl-kit` suite and **does not register an IM workspace**. Installation must be performed using the official command and requires DSH ≥ 0.1.2 and a configured `deepseek-flash` model. Its core features include specifying paths, filtering directories, and displaying hidden items; the version is 0.1.1.
