Motivation

The symlink e2e cases added in #885 only check that files are reachable through the restored paths: vtt print-file dist/pkg/index.js in the vtt case, and require in the Nitro case. A restore that copied each link's target instead of recreating the link would pass them too. Replacing each restored link with a copy of its target leaves both cases passing, so they don't pin down what #885 fixed.

Changes

• vtt read-link <path> prints a link's target, and fails if the path isn't a symbolic link.
• output_globs___symlinks_restored_on_cache_hit: after each cache hit, vtt read-link dist/pkg must print store/pkg.
• nitro_build_restores_traced_dependency_links: check.cjs checks that node_modules/tslib and each package's node_modules/tslib are symbolic links into .nf3. It resolves both ends with realpath, so the output is the same with nf3's relative targets on Unix and its absolute junction targets on Windows.
