Subject: [PATCH] Fix CI workflows to use Yarn 4 (Berry) with corepack

- Add packageManager field to package.json for corepack
- Add .yarnrc.yml with node-modules linker
- Update all workflows to use corepack enable + yarn --immutable
- Remove yarn cache from actions/setup-node (incompatible with Yarn 4)
