ci: Consistent NPM versions via Corepack (#20400)

* core: add .npmrc baseline to block dependency lifecycle scripts

Set ignore-scripts=true at the repo root, plus engine-strict, save-exact,
audit, and prefer-offline. This neutralizes the dominant npm supply-chain
attack vector — postinstall scripts in transitive dependencies — at the
cost of requiring an explicit rebuild for the handful of packages that
legitimately need install scripts (esbuild, chromedriver, tree-sitter,
tree-sitter-json). The next commit wires that rebuild into the Makefile.

* core: route node installs through make to retire website preinstall hook

Make docs-install depend on a new root-node-install so the root deps
are guaranteed before the website install runs, removing the need for
the website/preinstall lifecycle script. Rebuild the small audited list
of trusted packages (esbuild, chromedriver, tree-sitter, tree-sitter-json)
after the web install so ignore-scripts=true remains the only path that
needs maintenance. web/README documents the new workflow.
