Compare installed versions of packages.

Looks like this problem is related to duplicated dependencies with different versions.

• Compare installed versions and skip if the package is suitable.
• Cache manifests to speed up fetching.

The new system to compare installed versions works with the following projects.

Tests

• Vite
• next.js
• Remix
• Monorepo

Found errors with Remix projects, multiple versions of esbuild are installed.

This is caused because a subdependency installs the version * (latest) before the fixed version of @remix-run/dev.

Potential fix

• Skip * versions and add it to __SKIPPED array.
• After all the dependencies and subdependencies are installed, try to install the __SKIPPED packages (ignore them if the package is already in the root node_modules.

Partially fixed, now some sub-dependencies are not installed because the .fnpm parent file is not updated.

Example

rollup-plugin-node-polyfills is a dependency of @esbuild-plugins/node-modules-polyfill.
The .fnpm file of @esbuild-plugins/node-modules-polyfill is empty which means that it's dependencies are not installed.
