fix(langgraph-chat): align @types/node with the shared catalog#656
Merged
Conversation
#653 centralized @types/node via the pnpm catalog and migrated every workspace project, but examples/langgraph-chat (merged around the same time in #644) was left on "^20". The regenerated lockfile dropped the @types/node@20.x package entry, leaving a dangling 20.19.35 reference for this example that breaks `pnpm install --frozen-lockfile` on every PR. Switch the example to "@types/node": "catalog:" like the other 12 examples and regenerate the lockfile so it resolves to the catalog's 22.19.19.
