Lido v3 stVaults (WIP)

Installing Dependencies

Remove the incorrect yarn package

sudo apt remove -y nodejs

Install the correct yarn package.

nvm install 22
nvm use 22
nvm alias default 22
node --version

Enable Corepack under Node 22 and activate yarn.

corepack enable
corepack prepare yarn@stable --activate
hash -r
which yarn
yarn --version

Expected: which yarn should point to a Corepack-managed path and yarn --version should return a normal Yarn version (e.g., 1.22.x or 3.x/4.x), not error.
