feat(lint): add node-builtin-specifier rule

[bartlomieju]

Adds a node-builtin-specifier lint rule that warns when a Node.js
built-in module is imported with a bare specifier (e.g. "fs") instead
of the required "node:" prefix (e.g. "node:fs"). It covers both
static imports and dynamic import() calls and provides an autofix that
adds the "node:" prefix.

The rule previously lived in deno_lint, where it carried its own
hardcoded copy of the Node built-in module list that had to be kept in
sync by hand. It is being removed there
(denoland/deno_lint#1532) and reintroduced here as an
extended CLI lint rule so it can reuse the canonical list that already
lives in ext/node (via node_resolver's
DenoIsBuiltInNodeModuleChecker). That gives a single source of truth
for which modules count as Node built-ins.

The rule is tagged recommended. Note that, unlike the original
deno_lint implementation which emitted at warning severity, this version
emits at the default (error) severity because the pinned deno_lint
release does not yet expose the per-diagnostic severity API. Once
deno_lint ships that API and we bump the dependency, this can be
switched back to a warning.
