Syncpack v14, Monorepo CLI tool

Syncpack is a pragmatic, focused tool: it finds/fixes version mismatches, enforces version policies, can ban packages, and even source truth from specific packages — all from the CLI. The v14 Rust rewrite is a meaningful engineering move (likely faster and more robust) rather than a vanity bump, and the docs show sensible commands like npx syncpack list/update and workspace-aware discovery. Not revolutionary — this space has other solutions — but if you run a large monorepo and care about semver hygiene, it’s the kind of low-friction tool you’ll actually keep in devDependencies.
