// Created based on https://github.com/element-hq/element-call/blob/60fae70a60e3697eb41210ccf1e400cab37df7c8/.yarn/plugins/linker.cjs
// and the following prompt history:
// - Can you convert this yarn plugin into a pnpm plugin.
// - The goal is to not have modifications to the package.json and lock files so that we do not track links on gh.
// This seems to modify the package.json file.
// What can we do with pnpm to have the link inforamtion in a seperate file
// - why do you cache the loaded links. When does this file get executed?
// Do we need this optimization.
// How do we guarantee, that we aleays use the most recent content from the links file?
//
// Manual transition to cjs. Claude proposed manual yaml parsing.
