[Feature Request] Deep analyze of Cache Invalidation

Deep analyze of Cache Invalidation

Motivation

Perfsee can now calculate 'cache invalidation' from manifest info, but doesn't know whether the invalidation is as expected or not. And no help in troubleshooting if it does not match expectations‖.

The problem is detailed in https://webpack.js.org/concepts/manifest/#the-problem.

Detailed design

1. webpack/rollup/vite plugin upload all js assets to perfsee server at build time. (May need a S3 to store the assets).
2. Compare file content between disappearing files and new files.

Demo:

Alternatives

Analyze content diff locally: checkout - build - compare.
