fix(templates): use hoisted node-linker so Hugo v0.161 can resolve tailwindcss

Hugo v0.161's css.TailwindCSS reads node_modules/.bin/tailwindcss and
expects either a symlink or a Node-shebang script. pnpm's default
isolated linker creates shell wrappers (#!/bin/sh with NODE_PATH
manipulation), which Hugo rejects with "binary tailwindcss is not a
Node.js script". With node-linker=hoisted, pnpm flattens node_modules
and creates plain symlinks for Node-shebang bins — same shape npm
produces, which Hugo handles via its symlink branch in resolveNodeBin
(common/hexec/exec.go).

- Add .npmrc with node-linker=hoisted to all 9 templates and test/
- Verified end-to-end: academic-cv builds cleanly against published
  modules/blox with Hugo v0.161.1
- Kit root and modules/blox keep pnpm's isolated linker for monorepo
