- update MODULES.md to document dual-entry pattern (main vs ./client) and explain why client entry must not import server-only code - filter client manifest to only include modules exposing a `./client` subpath export - add `moduleHasClientEntry` helper in discover.server.js to check package.json exports - update cli.js to use `moduleHasClientEntry` when rendering the client manifest - update init.js and modules/index.js to align with new client entry convention
