dsh-context-badge: DSH Local Context and Todo Management

`dsh-context-badge` is a local-first plugin for DeepSeek Harness (DSH), designed to address session context logging and task tracking. It leverages browser local storage and an optional macOS companion app to provide lightweight state management. Core features include displaying context badges in the Dock, automatically saving notes and to-do items, generating local purpose-line summaries, and switching or managing session and workspace contexts. The plugin does not rely on remote synchronization or model calls; all data is stored locally, with a focus on privacy and data isolation, making it ideal for developers who frequently switch between workspaces.
