Scan all GraphQL type files under libs/shared/src/graphQL/types/ to find duplicate or structurally equivalent sub-types across files, then consolidate them into shared declarations and replace local copies with imports.

Scaffold a new Filter or Processing node in the playlist-maker custom app. Use when the user asks to add, create, or scaffold a playlist-maker node, or wants to extend the set of nodes available in the playlist-maker editor. Handles the full wiring (type union, processor, React component, three mapping files, sidebar entry, test file). Filter and Processing categories only — Source and Result are out of scope.
