fix(vendor): link Cordis workspaces in built artifacts

vendor/README.md

@@ -2,7 +2,7 @@
 
 This directory contains source-vendored copies of the Cordis framework and its foundation libraries. They are copied into this monorepo instead of being depended on via npm, so that the harness fully owns its framework layer (auditable, patchable, pinned).
 
-All vendored packages keep their **original npm names** (they are resolved through pnpm workspaces) and are marked `private: true` — they are never published from this repo. Upstream MIT `LICENSE` files are preserved in each package directory.
+All vendored packages keep their **original npm names** and are marked `private: true` — they are never published from this repo. `pnpm-workspace.yaml#linkWorkspacePackages` makes matching upstream semver ranges resolve these pinned workspaces, including imports from built `lib/`; disabling it substitutes npm copies behind the same names. Schemastery's manifest additionally declares a conditional `exports` map (import → `.mjs`, require → `.cjs`): pnpm links the directory itself, so without `exports` Node's ESM resolver would fall back to `main` and load the CJS entry whose lazy `require('cosmokit')` can race ESM loading of the same linked module under module-hook hosts (vitest). Upstream MIT `LICENSE` files are preserved in each package directory.
 
 This file covers the manifest, the local-modification log, and the procedure for **updating** an existing vendored package. To **add a new** one, see the cookbook guide: [docs/cookbook/adding-a-vendored-package.md](../docs/cookbook/adding-a-vendored-package.md).
