Bump pnpm to 12

pnpm 11 removed onlyBuiltDependencies in favour of allowBuilds and stopped reading non-auth settings from .npmrc, so auto-install-peers moves to pnpm-workspace.yaml. The native publish flow in pnpm 11+ keeps npm trusted publishing working as long as pnpm/action-setup is v6 or later.
