* Dev preflight for `pnpm --dir packages/desktop start` (and the root `pnpm desktop`):

* verify everything a source run needs, and fail with the actual fix instead of a bare

|
* ERR_MODULE_NOT_FOUND. The classic trap: this package's node_modules holds pnpm
|
|
* *injected copies* of the workspace packages, which only sync while building THROUGH
|
|
* pnpm — a stale copy surfaces as `Cannot find module …/penguin-server/dist/lock.js`.
