559a9a17 - fix: expose chainNodeStreams via entry-base instead of direct require in app-page template

fix: expose chainNodeStreams via entry-base instead of direct require in app-page template app-page.ts is a build template compiled by the user's bundler, so relative requires resolve from the project root and fail with webpack. Export chainNodeStreams from entry-base.ts (pre-compiled runtime bundle) and use entryBase.chainNodeStreams in the template instead. Also update CLAUDE.md with test output efficiency tip and correct the app-page.ts require guidance.
