DeepSeek Harness Plugin: dsh-wsl-registry (Read-Only Access to the Windows Registry from WSL)

`dsh-wsl-registry` is a plugin for DeepSeek Harness (DSH) that provides secure, read-only access to the Windows Registry for DSH instances running in WSL. By enforcing a strict access allowlist (such as `HKLM:\SOFTWARE` and `HKCU:\SOFTWARE`) and length limits, it permits reading only from specific registry areas and blocks sensitive paths such as `Run` and `RunOnce` to ensure safe operation. After installation, users can read key values with the `win_reg` command. It is intended for scenarios where the DSH process runs inside WSL and the DSH version is 0.1.2 or higher.
