Fix Cloudflare Workers build: use source exports for workspace, dist for npm publish

- Package exports now point to source files (./src/index.tsx) for workspace
  consumers, allowing Next.js/Turbopack to resolve without pre-building
- Added publishConfig swap script that switches exports to dist/ during
  npm publish (prepublishOnly) and back to source after (postpublish)
- Added @supermemory/memory-graph to transpilePackages in web app next.config.ts
  so Next.js transpiles the source files correctly
