dsh-notion-plugin: Using Notion MCP in DSH with 12 Cookbook Skills

craigary ported the official Notion claude-code-notion-plugin to a DSH Cordis bundle. The plugin connects to Notion-hosted MCP via local OAuth (localhost:53682) and an MCP proxy (localhost:53683), providing tools for searching, reading, and writing pages and databases, 12 independently toggleable skills, multi-workspace switching, and opening/reading the current page in the sidebar. It is not on the registry and requires local installation via `plugin_manager install_bundle`; note that sidebar sessions are non-persistent and require repeated login. MIT 0.1.4.
