Find unused files, exports and package dependencies with knip, configured for this Yarn workspaces monorepo: resolve the @excalidraw/* path aliases from tsconfig.json and vitest.config.mts, and treat each package's exports, excalidraw-app/index.tsx, setupTests.ts and the scripts run from package.json as entry points. Then check each candidate by removing it on a scratch branch and running yarn test:typecheck, yarn test:code, yarn build:packages, yarn build and yarn test:app --watch=false. Write dead-code.md listing only what passed that check, grouped into files, exports and dependencies, each with its path and the command output that proved it. List exports of published packages separately as public API, and list every candidate that failed the check with the error. Do not push or open a pull request."}
