Description
Using this plugin within a pnpm workspace monorepo does not properly augment the types on fastify's Request object.
In a standalone single package repo, it works fine, but as soon as workspaces is introduced, it fails.
Please look at the README in the linked repo to see the error.

Expected Behavior

I don't know pnpm, but if you find a fix and can push a PR I'll take a look.

Hmm, it might not be fixable. The only thing I've found to work is to not disable hoisting for fastify plugin packages.
