pnpm cheatsheet

copypnpm add -D vitest               # dev dep
pnpm dlx create-next-app         # run without installing
pnpm -F web dev                  # run a script in one workspace pkg
pnpm -r build                    # run recursively across all packages
pnpm up -i -L                    # interactive upgrade to latest
pnpm why react                   # who pulls in this dep

-F (filter) + -r (recursive) are the two flags that unlock monorepos.
