Run #1855: `npm install -g pnpm@…` failed with EEXIST because the runner's persistent hostedtoolcache Node install still carries the corepack `pnpm` shim from earlier `corepack enable` runs, and npm won't overwrite it. Disable/remove the shim first, then install, and print the version so the log shows which pnpm actually ran.
