@ahiosuz/dsh-workspace-tools: Auto-Apply DeepSeek Harness Workspace Presets

`@ahiosuz/dsh-workspace-tools` is a DeepSeek Harness plugin designed to eliminate the tedious process of repeatedly configuring Agent and permission presets when switching workspaces. It allows users to configure default rules for each workspace in the settings and automatically applies the corresponding workspace presets when a new root session is created. The plugin only affects new sessions, manual selections take precedence, and it is fully secure, with no access to sensitive data.
