Two targeted fixes: a Next.js and Turbopack build crash, and npm save-prefix mirroring.

Next.js and Turbopack with Tailwind v4

On the fast tier (Node 22.15+), Nub's sync resolve hook now recovers when a user async loader is active and Node routes a sync resolution into the async-hooks stub that throws a method-not-implemented error. This unblocks nub run build in real Next.js apps using Tailwind v4 with Turbopack, which previously aborted while evaluating globals.css and triggered an esbuild deadlock. The recovery branch fires only for the impossible sync-into-async hop; the user's async loader still runs for everything else. (#98)

npm save-prefix mirroring

When the incumbent package manager is npm, nub add <pkg> writes the saved specifier with npm's default save-prefix applied (^1.2.3), matching real npm install. The save-prefix and save-exact .npmrc settings are honored. pnpm, bun, and Nub-identity projects keep literal-preserve, and an explicit range is preserved verbatim on every package manager. (#97)
