In the latest Nub `nubx` lets you disable dlx (downloading packages from the internet) globally, forever
This lets you use nubx to invoke project-local CLIs (e.g. prisma, etc) without the risk of a typo running an untrusted package on your machine

Nub v0.9.1 — Nub autosizes the libuv threadpool on beefier machines
Node caps the threadpool at 4. Nub lets this float to the number of machine cores (with conservative nicing beyond 4), increasing max throughput for crypto, zlib, DNS, and native addons like bcrypt and sharp

New in Zod 4.6 — .validate()
Unlike .parse(), this method returns a boolean, aborts early when it encounters the first error, and instantiates no issue objects. It is 13-39x faster than `.safeParse().success` on invalid data.
