pnpm 12 reaches stable with Rust rewrite and lockfile fixes

pnpm 12 is now stable as a Rust rewrite that keeps pnpm 11 commands, flags, settings, and lockfile format compatible.

It canonicalizes peer resolution for cyclic dependency graphs, producing deterministic lockfiles while reporting 2–3× faster resolution and about 25% lower memory use on large cycle-heavy workspaces.

The release also changes hosted Git dependency resolution, reports unknown workspace settings, and adds project-aware global shims plus package-manager provisioning.
