dsh-clinepass-deepseekv4.1: A Pinned Solution for Integrating Cline Pass into DeepSeek Harness

The `dsh-clinepass-deepseekv4.1` plugin integrates Cline Pass to force all traffic through DeepSeek’s official channel, addressing routing configuration and usage monitoring issues. Its core is a local interception mechanism that inspects the `routing` metadata when a response is received; if a non-DeepSeek route is detected, it blocks non-compliant traffic via a streaming “retraction” or a non-streaming error. The plugin manages API keys and usage via DSH's native UI and offers three-tier validation modes: `strict`, `warn`, and `off`. Note that this is an unofficially maintained snapshot project, relies on DSH's internal behavior, and may break if upstream behavior changes.
